Author of Fluid Mechanics Fundamentals and Applications PDF

Yunus A. Çengel is Professor Emeritus of Mechanical Engineering at the University of Nevada, Reno. He received his B.S. in mechanical engineering from Istanbul Technical University and his M.S. and Ph.D. in mechanical engineering from North Carolina State University.

His research areas are renewable energy, desalination, exergy analysis, heat transfer enhancement, radiation heat transfer, and energy conservation.

He served as the director of the Industrial Assessment Center (IAC) at the University of Nevada, Reno, from 1996 to 2000.

He has led teams of engineering students to numerous manufacturing facilities in Northern Nevada and California to do industrial assessments and has prepared energy conservation, waste minimization, and productivity enhancement reports for them.

Dr. Çengel is the co-author of the widely adopted textbook Thermodynamics: An Engineering Approach, 8th edition (2015), published by McGraw-Hill Education.

He is also the co-author of the textbook Heat and Mass Transfer: Fundamentals & Applications, 5th Edition (2015), and the co-author of the textbook Fundamentals of Thermal-Fluid Sciences, 5th edition (2017), both published by McGraw-Hill Education.

Some of his textbooks have been translated to Chinese, Japanese, Korean, Spanish, Turkish, Italian, and Greek.

Dr. Çengel is the recipient of several outstanding teacher awards, and he has received the ASEE Meriam/Wiley Distinguished Author Award for excellence in authorship in 1992 and again in 2000.

Dr. Çengel is a registered Professional Engineer in the State of Nevada and is a member of the American Society of Mechanical Engineers (ASME) and the American Society for Engineering Education (ASEE).

John M. Cimbala is Professor of Mechanical Engineering at The Pennsylvania State University, University Park.

He received his B.S. in Aerospace Engineering from Penn State and his M.S. in Aeronautics from the California Institute of Technology (CalTech). He received his Ph.D. in Aeronautics from CalTech in 1984 under the supervision of Professor Anatol Roshko, to whom he will be forever grateful.

His research areas include experimental and computational fluid mechanics and heat transfer, turbulence, turbulence modeling, turbomachinery, indoor air quality, and air pollution control.

Professor Cimbala completed sabbatical leaves at NASA Langley Research Center (1993–94), where he advanced his knowledge of computational fluid dynamics (CFD), and at Weir American Hydro (2010–11), where he performed CFD analyses to assist in the design of hydro turbines.

Dr. Cimbala is the co-author of three other textbooks: Indoor Air Quality Engineering: Environmental Health and Control of Indoor Pollutants (2003), published by Marcel-Dekker, Inc.; Essentials of Fluid Mechanics: Fundamentals and Applications (2008);

and Fundamentals of Thermal-Fluid Sciences, 5th edition (2017), both published by McGraw-Hill Education.

He has also contributed to parts of other books and is the author or co-author of dozens of journal and conference papers. He has also recently ventured into writing novels. More information can be found at www.mne.psu.edu/cimbala.

Professor Cimbala is the recipient of several outstanding teaching awards and views his book writing as an extension of his love of teaching.

He is a member of the American Society of Mechanical Engineers (ASME), the American Society for Engineering Education (ASEE), and the American Physical Society (APS).

Preface to Fluid Mechanics Fundamentals and Applications eBook


Fluid mechanics is an exciting and fascinating subject with unlimited practical applications ranging from microscopic biological systems to automobiles, airplanes, and spacecraft propulsion.

Fluid mechanics has also historically been one of the most challenging subjects for undergraduate students because proper analysis of fluid mechanics problems requires not only knowledge of the concepts but also physical intuition and experience.

Our hope is that this book, through its careful explanations of concepts and its use of numerous practical examples, sketches, figures, and photographs, bridges the gap between knowledge and the proper application of that knowledge.

Fluid mechanics is a mature subject; the basic equations and approximations are well established and can be found in any introductory textbook.

Our book is distinguished from other introductory books because we present the subject in a progressive order from simple to more difficult, building each chapter upon foundations laid down in earlier chapters.

We provide more diagrams and photographs than other books because fluid mechanics is, by its nature, a highly visual subject. Only by illustrating the concepts discussed, can students fully appreciate the mathematical significance of the material.


This book has been written for the first fluid mechanics course for undergraduate engineering students. There is sufficient material for a two-course sequence if desired. We assume that readers will have an adequate background in calculus, physics, engineering mechanics, and thermodynamics. The objectives of this text are

  • To present the basic principles and equations of fluid mechanics.
  • To show numerous and diverse real-world engineering examples to give the student the intuition necessary for correct application of fluid mechanics principles in engineering applications.
  • To develop an intuitive understanding of fluid mechanics by emphasizing the physics, and reinforcing that understanding through illustrative figures and photographs

The book contains enough material to allow considerable flexibility in teaching the course. Aeronautics and aerospace engineers might emphasize potential flow, drag and lift, compressible flow, turbomachinery,

And CFD, while mechanical or civil engineering instructors might choose to emphasize pipe flows and open-channel flows, respectively.

New to Fluid Mechanics Fundamentals and Applications 4th Edition

All the popular features of the previous editions have been retained while new ones have been added. The main body of the text remains largely unchanged. A noticeable change is the addition of a number of exciting new pictures throughout the book.

Four new subsections have been added: “Uniform versus Nonuniform Flow” and “Equation Solvers” to Chap. 1, “Flying in Nature” by guest author Azar Eslam Panah of Penn State Berks to Chap. 11, and “CFD Methods for Two-Phase Flows” by guest author Alex Rattner of Penn State to Chap. 15.

In Chap. 8, we now highlight the explicit Churchill equation as an alternative to the implicit Colebrook equation. Two new Application Spotlights have been added: “Smelling Food; the Human Airway” by Rui Ni of Penn State, to Chap. 4,

And “Multicolor Particle Shadow Velocimetry/Accelerometry” by Michael McPhail and Michael Krane of Penn State to Chap. 8.

A large number of the end-of-chapter problems in the text have been modified and many problems were replaced by new ones. Also, several of the solved example problems have been replaced.
