PrefaceGeneral Approach
The fifth edition of Fluid Mechanics includes a number of additions and deletions, but no change in the philosophy of the book . The basic outline of eleven chapters, plus appendices, remains the same. The triad of integral, differential, and experimental approaches is retained. New problem exercises have been added, and many problems and worked examples have been changed. The informal, student-oriented style is retained. A number of new photographs and figures have been added.Learning Tools
The total number of problem exercises continues to increase, from 1089 in the 1st edition, 1169 in the 2nd, 1392 in the 3rd, 1500 in the 4th, and now 1650 in this 5th edition. Most of these are basic end-of -chapter problems, classified according to topic. There are also Word Problems, multiple-choice Fundamentals of Engineering Problems, Comprehensive Problems, and Design Projects. The appendix lists Answers to Selected Problems.
The example problems have been newly restructured throughout the text, following the sequence of steps outlined in Sect. 1.13 in order to provide a uniform problem-solving approach for students.
The Engineering Equation Solver (EES), described in Appendix E, is bound-in with the text, and continues its role as an attractive software tool for modeling and solving fluid mechanics and, indeed, other engineering problems. Not only is EES an excellent solver; it also contains thermophysical properties, publication-quality plotting, units checking, and many mathematical functions. The author is indebted to Sanford Klein and William Beckman, of the University of Wisconsin and F-Chart Inc., for invaluable and continuous help in preparing and updating EES for use in this text.Content Changes
There are some revisions in each chapter. Chapter 1 has been toned down considerably, with heavier topics moved to later chapters. New discussion and figures have been added on the important topic of flow visualization.
Chapter 2 has added new material on pressure transducers.
Chapter 3 introduces a list of specific suggestions on handling the difficult linear momentum equation. Bernoulli’s equation still comes last and is not broken out into a new chapter. I try to stress that the Bernoulli relation is dangerously restricted, and is often misused by both students and graduate engineers.
Chapter 4 now includes the derivation of laminar Poiseuille pipe flow, as an example of an exact solution to the Navier-Stokes equation. The topic is revisited briefly in Chapter 6. If you disagree with this sequence, just hold back and treat Sections 4.10 and 4.11 later in your course.
Chapter 5 now has a complete section on the selection of scaling variables for a dimensional analysis. By deciding in advance how to scale and present the data, ambiguity is reduced or eliminated.
Chapter 6 has added a new section on head loss and friction factor. Laminar and turbulent pipe flow have been separated for greater clarity. Turbulence modeling has been broken out as a separate section. New data have been added on minor losses, and new flow meters have been discussed. Orifice and nozzle meters now include the compressible-flow correction factor.
Chapter 7 has new discussion of computational fluid dynamics (CFD) and more detail on the boundary-layer approximations. A new section has been added on creeping flow.
Chapter 8, except for new problems and references, is much the same. I suspect that this is the most extensive treatment of potential flow in an undergraduate text.
Chapter 9 has more discussion of Fanno and Rayleigh flow and presents some of the new trends in aeronautics, both subsonic and supersonic.
Chapter 10 has more discussion of Froude number and has improved the treatment of gradually varied flow transitions, thanks to Professor Bruce E. LaRock of the University of California, Davis. A simple finite-difference varied-flow scheme has been added that is useful when field measurements are sparse. The concept of a compound weir has been introduced.
Chapter 11 is much the same, except for improvements and corrections suggested by Professor Gordon Holloway of the University of New Brunswick.Supplements
The Student Resources CD ROM contains the Limited Academic Version of the EES program; information on use of the software; and scripted EES problems from the textbook. The Limited Academic Version is a scaled-down version of EES that does not expire; the full Academic Version of EES, which needs to be renewed annually through use of a new password, is also available to adoptors of Fluid Mechanics, by downloading from the EES website as before.TheBook Website contains a Student Study Guide, prepared by Professor Jerry Dunn of Texas Tech University, that provides a concise review of all major topics covered in a first course; interactive versions of the FE Exam questions found in the text, prepared by Professor Edward Anderson of Texas Tech University, that are suitable for exam preparation or for self-testing; a link to the EES website; and PowerPoint versions of all text figures.
TheSolutions Manual provides complete and detailed solutions, including problems statements and art work, to all the end-of-chapter problems.Acknowledgments
As usual, so many people have helped me that I cannot remember or list them all. Throughout the writing, many much-appreciated suggestions and improvements were given by Gordon Holloway of the University of New Brunswick. All of the revisions and additions, including the Solutions Manual, were read and perfected by my colleague Elizabeth J. Kenyon. Many other reviewers and correspondents gave helpful suggestions, encouragement, corrections, and materials: Alex Smits, Princeton University; Ray Taghavi, University of Kansas; Ganesh Raman, Illinois Institute of Technology; Phil Combs, B.
