What’s New

  • Finite Control Volume Analysis A new section has been included to enhance student understanding of the energy equation.
  • Compressible Flow A new section covering compressibility effects on external flow has been added and includes a new example problem.
  • Reserve Problems and More Online Resources Approximately 225 new Reserve Assessment Problems emphasizing engineering applications have been added to this edition. Reserve Problems are not available to students unless they are assigned by an instructor, so solutions are more secure.

Instructor Resources

  • WileyPLUS provides instructor resources, such as the Instructor Solutions Manual, containing complete, detailed solutions to all of the problems in the text, Reserve Assessment Problems, additional problems, and figures from the text appropriate for use in lecture slides.

Andrew L. Gerhart, Professor of Mechanical Engineering at Lawrence Technological University, received his BSME degree from the University of Evansville in 1996, his MSME from the University of Wyoming, and his Ph.D. in Mechanical Engineering from the University of New Mexico.

At Lawrence Tech, Dr. Gerhart has developed both undergraduate and graduate courses in viscous flow, turbulence, creative problem solving, and first‐year introductory engineering. He has co‐developed college‐wide curriculum in engineering design and university‐wide curriculum in leadership. He is the supervisor of the Thermal Science and Aerodynamics Laboratories, Coordinator of the Aeronautical Engineering Minor/Certificate, chair of the First Year Engineering curriculum committee, and faculty advisor for the student branch of the American Institute of Aeronautics and Astronautics and the SAE Aero Design team.

Dr. Gerhart facilitates workshops worldwide, having trained hundreds of faculty members in active, collaborative, and problem‐based learning, as well as training professional engineers and students in creative problem solving and innovation. He is a member of the American Society for Engineering Education and has received four best paper awards from their Annual Conferences.

Dr. Gerhart was awarded the 2010 Michigan Professor of the Year by the Carnegie Foundation for the Advancement of Teaching and the Council for Advancement and Support of Education, Lawrence Tech’s Henry and Barbara Horldt Excellence in Teaching Award, the Engineering Society of Detroit’s (ESD) Outstanding Young Engineer, and ESD’s Council Leadership Award. He was elected to ESD’s College of Fellows, and is actively involved with The American Society of Mechanical Engineers, serving on the Performance Test Code Committee for Air‐Cooled Condensers.


Philip M. Gerhart, Dean of Engineering and Computer Science and Professor of Mechanical and Civil Engineering at the University of Evansville received his BSME degree from Rose-Hulman Institute of Technology in 1968 and his M.S. and Ph.D. degrees in Mechanical Engineering from the University of Illinois at Urbana-Champaign in 1969 and 1971. Before becoming Chair of Mechanical and Civil Engineering at the University of Evansville, he taught at the University of Akron from 1971 to 1984.

Dr. Gerhart has taught a variety of courses in fluid mechanics and other thermo-fluid sciences. He has consulted widely in the power generation and process industries and has authored or coauthored two previous books on fluid mechanics and fluid machinery.

Since 1975, he has been deeply involved in the development of the American Society of Mechanical Engineers Performance Test Codes. He served as ASME Vice President for Performance Test Codes from 1998 to 2001, as member and vice-chair of the Committee on Fans, as chair of the Committee on Fired Steam Generators, and as a member of the Standing Committee on Performance Test Codes.

Dr. Gerhart is a member of the American Society for Engineering Education and is a Life Fellow of the American Society of Mechanical Engineers. His honors and awards include the Outstanding Teacher Award from the Faculty Senate of the United Methodist Church, the Performance Test Codes Medal from ASME, and the Silver Beaver from the Boy Scouts of America.


John I. Hochstein, Professor of Mechanical Engineering at the University of Memphis, received a BE from Stevens Institute of Technology in 1973, the M.S. in Mechanical Engineering from the Pennsylvania State University in 1979, and his Ph.D. in Mechanical Engineering from the University of Akron in 1984. He has been on the faculty of the mechanical engineering department at the University of Memphis since 1991 and served as department chair from 1996-2014.

Working as an engineer in non-academic positions, Dr. Hochstein contributed to the design of the Ohio-Class submarines at the Electric Boat Division of General Dynamics and to the design of the Clinch River Breeder Reactor while an engineer at the Babcock & Wilcox Company. The focus of his doctoral studies was computational modeling of spacecraft cryogenic propellant management systems and he has remained involved with NASA research on this topic since that time. Dr. Hochstein has twice been a NASA Summer Faculty Fellow for two consecutive summers: once at the NASA Lewis (now Glenn) Research Center, and once at the NASA Marshal Spaceflight Center. Dr. Hochstein’s current primary research focus is on the capture of hydrokinetic energy to produce electricity.

Dr. Hochstein is an Associate Fellow of AIAA and has served on the Microgravity Space Processes Technical Committee since 1986. He joined ASME as an undergraduate student and served for 4 years on the K20 Computational Heat Transfer Committee. He is a member of ASEE and he has served the profession as an ABET Program Evaluator since 2002.
