Comprehensiveness rating: 2 read less
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
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.
Relevance/Longevity rating: 2
This book does not contain any most recent development in the field of fluid mechanics. Many subject index and author index provided at the end of book need to be updated. I don't know what mechanism that author used to update this book. In my opinion, there are plenty of improvements needed. The author does not seem to have an efficient way to manage the updates. I noticed some inconsistencies resulting from the different updates.
Clarity rating: 2
The clarity of the text is significantly hampered by the grammar errors, poorly-written sentences and inconsistencies, which is largely caused by the fact that English is only the third language of this author. The clarity of this book is also affected by the organization of materials, e.g. many technical terms are used before they are officially introduced (or some of them are not even introduced in this book).
Consistency rating: 2
My comment is based on the pdf version in July, 2013. There are some inconsistencies in the usage of terminology and framework. internally. Some portions do not seem to be completed. Some subjects laid out in Fig1.1 are not presented in this book.
Modularity rating: 3
The modularity of this book seems to be fine. There are clear divisions of sections and subsections.
Organization/Structure/Flow rating: 2
The general organization of the materials seems to be fine. However, when it comes to down more detailed knowledge, the book is not well organized. For example, the Bulk Modulus is presented even before the concept of Bulk Modulus is introduced. Some advanced subjects are introduced way before the readers have adequate exposure on the basics of fluid mechanics. Different types of instability are mentioned in different places. 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. In many chapters, the transition from section to section is abrupt.
Interface rating: 1
The quality of many figures do not fit textbook standards. It is impossible to see the labels in some of the figures because of the low quality of images or the tiny font sizes (e.g. Figure 1.6, 1.7 and many others). Some of the figures are poorly-made and quite confusing. There are also some inconsistencies in the layout of the different sections.
Grammatical Errors rating: 1
This book is full of conspicuous grammar errors including wrong spelling ("et al" was written as "at el", “pul” of “pull”, etc.), the misuse of tenses and active/passive voices, erroneous forms of verbs and improper prepositions, etc. I can easily find a sentence with 2-3 spelling errors. 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. For this book to become a textbook for English-speaking readers, significant improvement is needed on the writing.
Cultural Relevance rating: 5
I did not find anything that was culturally insensitive or offensive in any way.
