Thermodynamics: An Engineering Approach

Product Information

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.

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. Most outlines include basic theory, definitions, hundreds of example problems solved in step-by-step detail, and supplementary problems with answers. Some new examples and numerous new problems are added, including some extensive design problems. Many real-world problems dealing with thermoeconomics and the dollar value of various energy conservation measures are incorporated into various chapters to help students develop an understanding of the monetary value of energy. Some new problems deal with the environmental impact of energy conversion and energy conservation, and the emission of pollutants and greenhouse gases into the atmosphere.In Chap. 15, the section "Phase Equilibrium" is greatly expanded to include Henry's law and solid–gas phase equilibrium. 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: Connect is an online platform integrating ready-made course content with assessments and tools. The platform uses the most established adaptive digital technology to enhance teaching and learning, freeing up instructors to focus their own time and effort where it will have the most impact. Our philosophy that contributed to the popularity of the first two editions remains unchanged: talk directly to the minds of tomorrow’s engineers in a simple, yet precise manner and encourage creative thinking and development of a deeper understanding of the subject matter. Our goal in this undertaking was to offer an engineering textbook that is read by the students with interest and enthusiasm instead of one that is used as a reference book to solve problems. We wanted to touch the curious minds and take them to a pleasant journey in the wonderful world of thermodynamics where they could explore the wonders of this exciting science. The enthusiastic response we received from the users of the earlier editions from small colleges to large universities indicates that our objectives have been achieved.

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).The 10th edition of this introductory book retains all the popular features of the previous edition while providing updates for clarity and readability throughout the text. Some end-of-chapter problems in the text have been modified and some problems were replaced by new ones. Continue reading for a more detailed, chapter-by-chapter list of changes to the new edition. Available at most college bookstores, or for a complete list of titles and prices, write to: +Schaum Division Each title in this series is a complete and expert source of solved problems with solutions worked out in step-by-step detail. Thermodynamics is often perceived as a difficult subject, and the majority of students dread the experience. The authors believe, on the contrary, that thermodynamics is a simple subject, and an observant mind should have no difficulty understanding it. After all, the principles of thermodynamics are based on our everyday experiences and experimental observations. Thermodynamics is a mature basic science, and the topics covered in introductory texts are well established. Primarily, the texts differ only in the approach used. In this text, a more physical, intuitive approach is used throughout. Frequently, parallels are drawn between the subject matter and students’ everyday experiences so that they can relate the subject matter to what they already know. The new edition features an early introduction of the first law of thermodynamics, separate coverage of closed systems energy analysis, combined coverage of control volume mass and energy analysis, and revised coverage of compressible flow. Over 300 comprehensive problems have been added to this physically intuitive text, many of which come from industrial applications.

The traditional classical, or macroscopic, approach is used throughout the text, with microscopic arguments serving in a supporting role where appropriate. This approach is more in line with the students’ intuition and makes learning the subject matter much easier. 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.In Chap. 2, a new section, "Vapor Pressure and Phase Equilibrium" is added to expose students to the dynamics of phase-change processes and mass transfer. Also, Sec. 2-3 is expanded with discussions on some interesting consequences of the saturation temperature–pressure dependence. 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. 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. Recent information dealing with new developments in thermodynamic systems, such as the new generation of gas turbines with remarkable efficiencies, is incorporated throughout the text.

The Instructor’s Resource CD that is available to adopters contains PowerPoint presentation of key figures in the text and lecture outlines as well as the complete solutions manual, the EES problems disk, and the tables and charts from the appendix.

In Chap. 3, a new section "Refrigeration and Freezing of Foods" is added to show the relevance of thermodynamics to everyday life. Also, the first-law relation is redeveloped using an intuitive approach. Thermodynamics: An Engineering Approach is also available with Smartbook through the Connect platform.
