In fact, it is also related to disciplines like industrial engineering, and electrical engineering. While the emphasis is somewhat different in this book, the common material is presented and hopefully can be used by all. One can only admire the wonderful advances done by the previous geniuses who work in this field. In this book it is hoped to insert, what and when a certain model is suitable than other models. One of the difference in this book is the insertion of the introduction to multiphase flow. Clearly, multiphase is an advance topic. However, some minimal familiarity can be helpful for many engineers who have to deal with non pure single phase fluid. This book is the third book in the series of POTTO project books. POTTO project books are open content textbooks so everyone are welcome to joint in. The topic of fluid mechanics was chosen just to fill the introduction chapter to compressible flow. During the writing it became apparent that it should be a book in its own right. In writing the chapter on fluid statics, there was a realization that it is the best chapter written on this topic. It is hoped that the other chapters will be as good this one. This book is written in the spirit of my adviser and mentor E.R.G. Eckert. Eckert, aside from his research activity, wrote the book that brought a revolution in the education of the heat transfer. Up to Egret's book, the study of heat transfer was without any dimensional analysis. He wrote his book because he realized that the dimensional analysis utilized by him and his adviser (for the post doc), Ernst Schmidt, and their colleagues, must be taught in engineering classes. His book met strong criticism in which some called to \"burn\" his book. Today, however, there is no known place in world that does not teach according to Eckert's doctrine. It is assumed that the same kind of individual(s) who criticized Eckert's work will criticize this work. Indeed, the previous book, on compressible flow, met its opposition. For example, anonymous Wikipedia user name EMBaero claimed that the material in the book is plagiarizing, he just doesn't know from where and what. Maybe that was the reason that he felt that is okay to plagiarize the book on Wikipedia. These criticisms will not change the future or the success of the ideas in this work. As a wise person says \"don't tell me that it is wrong, show me what is wrong\"; this is the only reply. With all the above, it must be emphasized that this book is not expected to revolutionize the field but change some of the way things are taught. The book is organized into several chapters which, as a traditional textbook, deals with a basic introduction to the fluid properties and concepts (under construction). The second chapter deals with Thermodynamics. The third book chapter is a review of mechanics. The next topic is statics. When the Static Chapter was written, this author did not realize that so many new ideas will be inserted into this topic. As traditional texts in this field, ideal flow will be presented with the issue of added mass and added forces (under construction). The classic issue of turbulence (and stability) will be presented. An introduction to multi-phase flow, not a traditional topic, will be presented next (again under construction). The next two chapters will deal with open channel flow and gas dynamics. At this stage, dimensional analysis will be present (again under construction).","contributors":[{"id":3693,"contribution":"Author","primary":true,"corporate":false,"title":null,"first_name":"Genick","middle_name":null,"last_name":"Bar-Meir","location":null,"background_text":"Genick Bar-Meir holds a Ph.D. in Mechanical Engineering from University of Minnesota and a Master in Fluid Mechanics from Tel Aviv University. Dr. Bar-Meir was the last student of the late Dr. R.G.E. Eckert. Much of his time has been spend doing research in the field of heat and mass transfer (related to renewal energy issues) and this includes fluid mechanics related to manufacturing processes and design. Currently, he spends time writing books (there are already three very popular books) and software for the POTTO project (see Potto Prologue). The author enjoys encouraging his students to understand the material beyond the basic requirements of exams. In his early part of his professional life, Bar-Meir was mainly interested in elegant models whether they have or not a practical applicability. Now, this author’s views had changed and the virtue of the practical part of any model becomes the essential part of his ideas, books and software. He developed models for Mass Transfer in high concentration that became a building block for many other models. These models are based on analytical solution to a family of equations. As the change in the view occurred, Bar-Meir developed models that explained several manufacturing processes such the rapid evacuation of gas from containers, the critical piston velocity in a partially filled chamber (related to hydraulic jump), application of supply and demand to rapid change power system and etc. All the models have practical applicability. These models have been extended by several research groups (needless to say with large research grants). For example, the Spanish Comision Interministerial provides grants TAP97-0489 and PB98-0007, and the CICYT and the European Commission provides 1FD97-2333 grants for minor aspects of that models. Moreover, the author’s models were used in numerical works, in GM, British industry, Spain, and Canada."}],"subjects":[{"id":53,"name":"Civil Engineering","parent_subject_id":13,"call_number":"TA1-2040","visible_textbooks_count":13,"url":"https://staging.open.umn.edu/opentextbooks/subjects/civil"},{"id":13,"name":"Engineering \u0026 Technology","parent_subject_id":null,"call_number":"TA145","visible_textbooks_count":119,"url":"https://staging.open.umn.edu/opentextbooks/subjects/engineering"},{"id":56,"name":"Mechanical Engineering","parent_subject_id":13,"call_number":"TJ1-1570","visible_textbooks_count":20,"url":"https://staging.open.umn.edu/opentextbooks/subjects/mechanical"}],"publishers":[{"id":51,"url":"https://www.potto.org/about.php","year":2021,"created_at":"2018-09-07T12:22:36.000-05:00","updated_at":"2022-01-20T19:09:29.000-06:00","name":"Potto Project"}],"formats":[{"id":878,"type":"PDF","url":"https://zenodo.org/records/17328511","price":{"cents":0,"currency_iso":"USD"},"isbn":null}],"rating":"3","textbook_reviews_count":9,"reviews":[{"id":217,"first_name":"Jiarong","last_name":"Hong","position":"Assistant Professor","institution_name":"University of Minnesota","comprehensiveness_rating":2,"comprehensiveness_review":"This book is intended to serve as an undergraduate textbook. Although it captures some core materials of fluid mechanics such as integral and differential analysis, it misses many important introductory concepts and materials that are suitable for undergraduate level and that are often emphasized in many other standard textbooks. The important materials that are missing include thorough discussions on Lagrangian and Eulerian perspectives, Bernoulli equation, pipe flows, detailed discussion on boundary layer, Drag and Lift, and the concept of laminar and turbulent flows, etc.  Specifically, there are only 2-3 paragraphs that introduce Lagrangian and Eulerian perspective very briefly. There is no discussion on laminar to turbulence transition, the classical flows over a flat plate and fully-developed pipe flows including famous Moody chart. There is very little discussion on Bernoulli equation, which is probably the most memorable element in the fluid mechanics for the undergraduates. These missing materials are extremely important because: (1) they reflect the unique nature of fluids; (2) they can be easily appreciated by undergraduates; (3) they are widely used in many engineering applications. Instead of focusing on these basic elements, the book introduces many materials that are rarely-seen from standard textbooks (e.g. Pushka equations and Nusselt’s methods) and that are mathematically complex, which cannot be easily absorbed by undergraduates.  The solutions for many example problems are incomplete, many of which the author did not put numerical values and just left the equations with \"=\". This book does not have any exercise problems for the students. However, it is meritorious that the book contains a chapter that reviews the classical mechanics and an appendix that summarizes the mathematics for fluid mechanics, which are very useful review materials for undergraduates to get ready for fluid mechanics.","accuracy_rating":2,"accuracy_review":"Considering the fact that this book contains so many grammar errors and inconsistencies, I am skeptical on the accuracy of some of materials that presented in this book. One example is on the discussion of surface tension. The book criticizes the explanation of surface tension from many other textbooks.  First of all, the book failed to provide a clear microscopic explanation of surface tension by itself. Second, I feel this book might misunderstand the usage of “imbalance” from some of standard textbooks (I did not check every single one of them). The second example is that this book has a long discussion on Nusselt’s technique in the chapter of dimensional analysis. The material is not included in any textbooks of fluid mechanics that I have seen before. I also did some search on google scholar, and I didn’t find much information related to the derivation and applications of this technique. So I don’t know whether this material has been well-accepted and justified by the fluid community.

The discussions on surface tension appear in different sections. In addition, there is a lack of overview or summary sentences that highlights the key messages from each and multiple subsections.

A portion of sentences are not well written and do not a good readability.  This is understandable since the English is only the third language of the author. However, it is evident that little time and attention have been paid to proofread this book, and to polish each sentence and the organization of sentences.

The main difference between compressible flow and almost incompressible flow is not the fact that compressibility has to be considered. Rather, the difference is in two phenomena that do not exist in incompressible flow. The first phenomenon is the very sharp discontinuity (jump) in the flow in properties. The second phenomenon is the choking of the flow. Choking is when downstream variations don't effect the flow. Though choking occurs in certain pipe flows in astronomy, there also are situations of choking in general (external) flow.","contributors":[{"id":2822,"contribution":"Author","primary":true,"corporate":false,"title":null,"first_name":"Genick","middle_name":null,"last_name":"Bar-Meir","location":null,"background_text":"Genick Bar-Meir holds a Ph.D. in Mechanical Engineering from University of Minnesota and a Master in Fluid Mechanics from Tel Aviv University. Dr. Bar-Meir was the last student of the late Dr. R.G.E. Eckert. Much of his time has been spend doing research in the field of heat and mass transfer (related to renewal energy issues) and this includes fluid mechanics related to manufacturing processes and design. Currently, he spends time writing books (there are already three very popular books) and softwares for the POTTO project (see Potto Prologue). The author enjoys to encourage his students to understand the material beyond the basic requirements of exams. In his early part of his professional life, Bar-Meir was mainly interested in elegant models whether they have or not a practical applicability. Now, this author’s views had changed and the virtue of the practical part of any model becomes the essential part of his ideas, books and software. He developed models for Mass Transfer in high concentration that became a building blocks for many other models. These models are based on analytical solution to a family of equations. As the change in the view occurred, Bar-Meir developed models that explained several manufacturing processes such the rapid evacuation of gas from containers, the critical piston velocity in a partially filled chamber (related to hydraulic jump), application of supply and demand to rapid change power system and etc. All the models have practical applicability. These models have been extended by several research groups (needless to say with large research grants). For example, the Spanish Comision Interministerial provides grants TAP97-0489 and PB98-0007, and the CICYT and the European Commission provides 1FD97-2333 grants for minor aspects of that models. Moreover, the author’s models were used in numerical works, in GM, British industry, Spain, and Canada. In the area of compressible flow, it was commonly believed and taught that there is only weak and strong shock and it is continue by Prandtl–Meyer function. Bar–Meir discovered the analytical solution for oblique shock and showed that there is a quiet bu?er between the oblique shock and Prandtl–Meyer. He also build analytical solution to several moving shock cases. He described and categorized the filling and evacuating of chamber by compressible fluid in which he also found analytical solutions to cases where the working fluid was ideal gas. The common explanation to Prandtl–Meyer function shows that flow can turn in a sharp corner. Engineers have constructed design that based on this conclusion. Bar-Meir demonstrated that common Prandtl–Meyer explanation violates the conservation of mass and therefor the turn must be around a finite radius. The author’s explanations on missing diameter and other issues in fanno flow and “naughty professor’s question” are used in the industry. In his book “Basics of Fluid Mechanics”, Bar-Meir demonstrated several things which include Pushka equation, dealing with the pressure accounted the slight compressibility (a ?nite Bulk Modulus effect), speed of sound in slightly compressible liquid. He showed the relationship between the wavy surface and the multi–phases flow. The author lives with his wife and three children. A past project of his was building a four stories house, practically from scratch. While he writes his programs and does other computer chores, he often feels clueless about computers and programing. While he is known to look like he knows a lot a lot about many things, the author just know to learn quickly. The author spent years working on the sea (ships) as a engine sea officer but now the author prefers to remain on a solid ground."}],"subjects":[{"id":13,"name":"Engineering \u0026 Technology","parent_subject_id":null,"call_number":"TA145","visible_textbooks_count":119,"url":"https://staging.open.umn.edu/opentextbooks/subjects/engineering"},{"id":56,"name":"Mechanical Engineering","parent_subject_id":13,"call_number":"TJ1-1570","visible_textbooks_count":20,"url":"https://staging.open.umn.edu/opentextbooks/subjects/mechanical"}],"publishers":[{"id":107,"url":"https://www.potto.org/downloadsGD.php","year":2021,"created_at":"2018-09-07T12:22:37.000-05:00","updated_at":"2022-01-20T18:58:41.000-06:00","name":"Potto Project"}],"formats":[{"id":877,"type":"Online","url":"https://zenodo.org/records/18217916","price":{"cents":0,"currency_iso":"USD"},"isbn":null},{"id":2594,"type":"PDF","url":"https://zenodo.org/records/18217916","price":{"cents":0,"currency_iso":"USD"},"isbn":null}],"rating":"3.5","textbook_reviews_count":2,"reviews":[{"id":1819,"first_name":"Brian","last_name":"Maicke","position":"Assistant Professor","institution_name":"Penn State University","comprehensiveness_rating":3,"comprehensiveness_review":"The textbook covers the major topics one would expect in an introductory textbook.  Major topics from an introductory compressible flow course like the speed of sound, Rayleigh and Fanno flow, variable area flows, normal and oblique shocks, and Prandtl-Meyer expansions have their own chapters.  The book also includes a review of thermodynamics and basic fluid mechanics.\n\nThere are several chapters that do not appear in standard compressible flow textbooks. These chapters deal with evacuating chambers and isothermal flow but these chapters are not as polished as the more standard chapters. As a work in progress, there are some sections of the textbook which are unfinished or have notes to the reader to ignore incomplete sections.  \n\nThe textbook only mentions computational fluid dynamics briefly in the introduction and does not have any in-depth material on CFD issues related to compressible flow.\n\nThe book has some compressible flow tables included within the body of the text, but no dedicated appendices like most compressible flow textbooks. The webpage for the textbook does have links to HTML, PDF, and the latex source files for compressible flow tables but they are on a supplemental download page and may not be immediately obvious to the reader.  The download page also features a compressible flow equation reference and a computer program for gas dynamics calculations.\n\nThe book includes a good table of contents, list of figures, and list of tables.  There is a subject index, but the coverage could be improved.  For example, there is a chapter on Isentropic flow but the word isentropic does not appear in the subject index.

In the main compressible flow chapters (normal and oblique shocks, Prandtl-Meyer expansion, Rayleigh and Fanno Flow, variable area flow, isentropic flow), the chapters are more polished and accurate.\n\nWhen dealing with the mathematics and science of compressible flow, the text is unbiased.  In the introduction and in some of the supplemental materials the author takes a more argumentative tone that may be off-putting to some readers.\n\n","relevance_rating":3,"relevance_review":"I see no issues with the relevance or longevity of most of the text.

Unfortunately, when performing a web search for the book, most readers will find the online textbook which has several significant issues.  First, the book is several revisions behind the PDF version of the text.  This could cause difficulties with students viewing the online textbook vs. the PDF version.  Second, at the time of this review, the PDF download of the textbook does not seem to be available on the Potto project page.  This reduced availability for the latest revision of the text greatly decreases the usefulness of the book as the later revisions added much-needed example problems and polish to the main compressible flow chapters.\n\nIf the availability of the latest PDF were corrected and the webpage updated, this score would increase.","grammatical_rating":2,"grammatical_review":"The text has many grammatical and typographical errors throughout the text.

The book covers all the needed areas (everything from basic blueprint reading to terminologies used in real world applications to interpretation of prints).  The text is written in simple language which makes it very easy to understand, particularly for its target audience (first year students that likely have little background or knowledge in this area).","accuracy_rating":5,"accuracy_review":"I found no bias built into this book.  While I did find that sometimes the terminology was used mixed together, that terminology was still accurate.

In my career, when we hire new people into my department, we have to give them blueprint training so that they will understand how to read and interpret blueprints.

This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material. The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman’s many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane.

Traditional analog modulation systems are also described. Systems trade-offs, including link budgets, are emphasized. Interactive graphics allow the students to engage with and visualize communication systems concepts. Interactivity and in-line review questions enables students to rapidly examine system tradeoffs and design alternatives.

There are interactive problems at the end of each chapter of the book which can be considered as a quick review of the book. Also, I found the trigonometric tables very useful for students who have forgotten basic geometry and trigonometry. One of the interesting parts of this book is using QR codes for which you can have access to dynamic pictures of the book. The only negative point that I can mention is the lack of enough sample problems for each content. Students who take Engineering Statics need to practice many problems/examples to get ready for their exams. Only one sample problem for most of the topics is not enough particularly for those who need time to understand the concepts through solving sample problems.

Students are expected to have some background in some of the fundamental concepts of the definition of a fluid, hydrostatics, use of control volume conservation principles, initial exposure to the Navier-Stokes equations, and some elements of flow kinematics, such as streamlines and vorticity. It is not meant to be an in-depth study of potential flow or viscous flow, but is meant to expose students to additional analysis techniques for both of these categories of flows. We will see applications to aerodynamics, with analysis methods able to determine forces on arbitrary bodies. We will also examine some of the exact solutions of the Navier-Stokes equations based on classical fluid mechanics. Finally we will explore the complexities of turbulent flows and how for boundary layer flows one can predict drag forces. This compilation is drafted from notes used in the course Intermediate Fluid Mechanics, offered to seniors and first year graduate students who have a background in mechanical engineering or a closely related area.","contributors":[{"id":5532,"contribution":"Author","primary":true,"corporate":false,"title":null,"first_name":"James","middle_name":null,"last_name":"Liburdy","location":"Oregon State University","background_text":"James Liburdy, Oregon State University"}],"subjects":[{"id":13,"name":"Engineering \u0026 Technology","parent_subject_id":null,"call_number":"TA145","visible_textbooks_count":119,"url":"https://staging.open.umn.edu/opentextbooks/subjects/engineering"},{"id":56,"name":"Mechanical Engineering","parent_subject_id":13,"call_number":"TJ1-1570","visible_textbooks_count":20,"url":"https://staging.open.umn.edu/opentextbooks/subjects/mechanical"}],"publishers":[{"id":1055,"url":null,"year":null,"created_at":"2021-09-27T19:06:15.000-05:00","updated_at":"2026-06-23T14:21:08.000-05:00","name":"Oregon State University"}],"formats":[{"id":2635,"type":"eBook","url":"https://open.oregonstate.education/intermediate-fluid-mechanics/","price":{"cents":0,"currency_iso":"USD"},"isbn":null},{"id":2636,"type":"PDF","url":"https://open.oregonstate.education/intermediate-fluid-mechanics/","price":{"cents":0,"currency_iso":"USD"},"isbn":null},{"id":2637,"type":"XML","url":"https://open.oregonstate.education/intermediate-fluid-mechanics/","price":{"cents":0,"currency_iso":"USD"},"isbn":null}],"rating":"4","textbook_reviews_count":2,"reviews":[{"id":33831,"first_name":"Derrel","last_name":"Fincher","position":"Assistant Instructional Professor","institution_name":"Pittsburg State University","comprehensiveness_rating":4,"comprehensiveness_review":"The book is compreshensive for the areas it covers, but it only has a table of contents and lacks both an index and a glossary.

An effective index and glossary would increase this rating to a five.","accuracy_rating":4,"accuracy_review":"I did not notice any content errors in the book although the print PDF version had Latex code showing instead of the symbol or equation in several areas.","relevance_rating":5,"relevance_review":"The content uses well-established theory.","clarity_rating":5,"clarity_review":"Overall, I found the prose clear and understandable.","consistency_rating":4,"consistency_review":"Overall the book is internally consistent, although I did find a couple of headings that used a different font and/or case than others at the same level.","modularity_rating":5,"modularity_review":"The book has an adequate number of subheadings that will make assigning readable \"chunks\" possible.","organization_rating":5,"organization_review":"Content is developed logically from previously introduced concepts.","interface_rating":4,"interface_review":"I used the Print PDF version for review. Overall, it was consistent, but in several captions, Latex code was present rather than the symbols. Overall, figures use vector graphics so they are clear at different zooms, but Figure 2.3 appears to be a PNG image rather than using vector graphics, so some of the curves and text have artifacts. Also, the lift coefficient equation is still in Latex rather than rendering as an equation.","grammatical_rating":5,"grammatical_review":"Overall, grammar is meets expectations and is internally consistent.","cultural_rating":5,"cultural_review":"The book does not have human actors, and does not reference cultural issues.","overall_rating":9,"overall_review":"Overall, I appreciated the book and found it to be a good refresher. It is primarily a reference book rather than a text book as it has no problems for students to work. The biggest drawback for me was lack of an index and glossary. The book referred several times to another book on Viscous Fluid Flow by F.M. White, and it would have been nice to have a full reference to the work in a references section.","created_at":"2022-05-05T11:30:02.000-05:00","updated_at":"2022-05-05T11:30:02.000-05:00"},{"id":34422,"first_name":"Fatma","last_name":"Elseid","position":"Lecturer of Engineering and Engineering Technology","institution_name":"Metropolitan State University of Denver","comprehensiveness_rating":3,"comprehensiveness_review":"The text does not cover all areas and ides of the topics, instead ,for example, briefly covers some topics such as CFD","accuracy_rating":4,"accuracy_review":"There are grammar mistakes but unbiased content.","relevance_rating":3,"relevance_review":"Content is not up-to-date, all topics is analysis of well-known fluid Mechanics equations, such as Bernoulli and Navier Stokes equations and are briefly discussed","clarity_rating":4,"clarity_review":"The text is written in a clear way and accessible, but some equations are written in complex way, for example, Bernoulli Equation is written in vector notation which makes it complicated for some readers.","consistency_rating":4,"consistency_review":"The text is consistent in terms of terminology and framework.","modularity_rating":4,"modularity_review":"The text is divided to smaller to moderate reading sections as needed and easy to read, there are titles and subtitles.","organization_rating":4,"organization_review":"The topics in the text are presented in a logical, and in some points also in clear fashion.","interface_rating":4,"interface_review":"The text is free of significant interface issues.
