Professors Çengel and Boles received the ASEE Meriam/Wiley Distinguished Author Award in 1992 in recognition of their excellence in the authorship of the first edition of this text. In the new Chapter 7, the coverage of Relative Pressure Pr and Relative Specific Volume vr used for isentropic processes of ideal gases, as well as their corresponding columns in the air tables in the Appendices (Tables A-17 and A-17E), are removed. Instead, a more versatile new entropy function s+ is defined for the first time and its values are listed in the air tables. The s+ function makes it possible to calculate the entropy change of ideal gases with variable specific heats when specific volume information is given instead of the pressure information. The existing so function together with the new s+ function allows us to do everything we could do with the functions Pr and vr, plus more.

Fluid Mechanics: Fundamentals and Applications is written for the first fluid mechanics course for undergraduate engineering students, with sufficient material for a two-course sequence. This Third Edition in SI Units has the same objectives and goals as previous editions:

We would like to take this opportunity to thank the many users of the first two editions at more than l50 colleges and universities in the United States and Canada and many others in several countries overseas for their comments, praises, and constructive criticism. Special thanks are due to faculty who reviewed the third edition with a critical eye and made valuable suggestions for improvements: The relations above reinforce that during an actual process, mass and energy are conserved, entropy is generated, and exergy is destroyed. Students are encouraged to use these forms of balances in early chapters after they specify the system and to simplify them for the particular problem. A more relaxed approach is used in later chapters. Dr Çengel is the recipient of several outstanding teacher awards, and he received the ASEE Meriam/Wiley Distinguished Author Award for excellence in authorship in 1992 and again in 2000. Each chapter contains numerous worked-out examples that clarify the material and illustrate the use of the basic principles. A consistent and systematic approach is used in the solution of the example problems, with particular attention to the proper use of units. A sketch and a process diagram are included for most examples to clearly illustrate the geometry and the type of process involved.

EES is particularly useful in thermodynamics problems since most property data needed for solving problems in these areas are provided by the program. For example, the steam tables are implemented such that any thermodynamic property can be obtained from a built-in function call in terms of any other properties. Similar capability is provided for all substances. EES also allows the user to enter property data or functional relationships with lookup tables, with internal functions written with EES, or with externally compiled functions written in Pascal, C, C++, or Fortran. Interesting practical problems that may have implicit solutions are often not assigned because of the mathematical complexity involved. EES allows the user to concentrate on concepts by freeing him or her from mundane chores. We are gratified by the enthusiastic response this book has received, and we hope that the improvements made in the new edition will make it even more appealing. Your comments and criticisms are always welcome and will be greatly appreciated. The material is introduced at a level that average students can follow comfortably. It speaks to the students, not over them. In fact, the material is self-instructive, thus freeing the instructor to use class time more productively.In the new Chapter 9 on exergy, we eliminated the use of the symbols Φ and ψ for the specific exergies of stationary masses and flowing fluids, and replaced them with xnonflow and xflow, respectively. This change ensures consistent use of the symbols x, X, and X for the specific, total, and time rate of exergy, in parallel to their counterparts e, E, and Ė for energy and s, S, and S for entropy. Also, we have enhanced the chapter with cryogenic applications to attract attention to the tremendous work potential of substances at low temperatures, such as LNG at about −160ºC. Further, we did away with the occasional use of the traditional sign convention by replacing the expression Q – W for the net energy transfer by the heat and work in the energy balance relations by Qnet, in + Wnet, in, with the remark that a negative quantity for the net heat or work term represents output instead of input. In Chap. 5, two new sections, "Energy Conversion Efficiencies" and "Household Refrigerators," are added. In the former section, combustion efficiency, motor efficiency, lighting efficiency, overall efficiency, and the heating values of fuels are presented. In the latter section, several ways of conserving energy while using a refrigerator are discussed. Dr Kanoğlu has taught at the University of Nevada, Reno; Ontario Tech University; American University of Sharjah; and the University of Gaziantep. He is the co-author of the books Fundamentals and Applications of Renewable Energy (1st ed., 2020) and Energy Efficiency and Management for Engineers (1st ed., 2020), both published by McGraw-Hill.

In Chap. 6, a new section "Reducing the Cost of Compressed Air" is added to expose future engineers to several practical ways of minimizing the power consumption of compressors, which is a significant fraction of the total energy consumption of most manufacturing facilities. Also, the entropy balance relation is redeveloped and moved to the end of the chapter. Alternatively, our dedicated Academic Consultants, Digital Success and Customer Support teams are there to help you discover the right solution for your needs. We can create a bespoke offering that will allow you to achieve the institutional and commercial objectives of your learning & teaching programme. The use of a formal sign convention for heat and work is de-emphasized. Instead, an intuitive and unified approach is adopted for interactions. The mass, energy, entropy, and exergy balances for any system undergoing any process are expressed asYunus 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 PhD in mechanical engineering from North Carolina State University. His areas of interest are renewable energy, energy efficiency, energy policies, heat transfer enhancement, and engineering education. He served as the Industrial Assessment Center (IAC) director 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 perform industrial assessments. He has prepared energy conservation, waste minimization, and productivity enhancement reports for them. He has also served as an advisor for various government organizations and corporations. In Chap. 15, the section "Phase Equilibrium" is greatly expanded to include Henry's law and solid–gas phase equilibrium.
