Features
NEW! 1st Law of Thermodynamics is introduced early in a new Chapter 2: Energy, Energy Transfer, and General Energy Analysis. This introductory chapter sets the framework to establish a general understanding for various forms of energy, mechanisms of energy transfer, the concept of energy balance, thermo-economics, and conversion efficiency using familiar settings that involve mostly electrical and mechanical forms of energy. This new organization offers a pedagogical breakthrough in teaching thermodynamics&emdash;motivating students early in the course while still providing a logical presentation of the fundamental concepts.
NEW! The energy analysis of closed systems is now presented in a separate chapter, Chapter 4, together with the boundary work and the discussion of specific heats for both ideal gases and incompressible substances.
NEW! The conservation of mass is now covered together with conservation of energy in the new Chapter 5 Mass and Energy Analysis of Control Volumes. A formal derivation of the general energy equation is also given in this chapter as a Topic of Special Interest.
NEW! The Chapter on Thermodynamics of High-Speed Flow is greatly revised and expanded. The new chapter 17 now includes the coverage of oblique shocks and flow with heat transfer (Rayleigh flow) with some exciting photographs of shock waves.
NEW! Over 300 new problems focusing on more difficult concepts and integrating industry-relevant topics further enhance the extensive and diverse text homework problem sets. In addition, approximately 40% of the current text homework problems sets have been revised.
NEW! Expanded photo program and updated art style with over 1,000 engaging illustrations provide a motivating visual program for the text. Our text features more illustrations and photographs than other books in this category. Some of the figures and photographs in the text are intended to serve as a means of emphasizing key concepts that would otherwise go unnoticed; some serve as page summaries.
NEW! Learning Objectives have been added to each chapter of the text along with an ABET Guide to show how the text coverage, features, and supplements help achieve ABET objectives.
NEW! An updated Interactive Thermodynamics Tutorial is now tied to directly to the text with an icon to indicate when students should refer to the tutorial to further explore difficult topics such as Entropy and the 2nd Law of Thermodynamics.
An emphasis on physics, focuses the text presentation on the physical aspects of the subject matter in addition to mathematical representations and manipulations. The authors believe that the emphasis in undergraduate education should remain on developing a sense of the underlying physical mechanisms and a mastery of solving practical problems that an engineer is likely to face in the real world.
A systematic solution procedure for worked examples provides a well-structured approach to problem solving while maintaining an informal, conversational style. The problem is first stated and the objectives are identified, then the assumptions made are stated together with their justifications. The properties needed to solve the problem are listed separately. Numerical values are used together with their units to emphasize that numbers without units are meaningless, and unit manipulations are as important as manipulating the numerical values with the calculator. The significance of the findings is discussed following the solutions. This approach is also used consistently in the Instructor’s Solutions Manual.
"Topics of Special Interest," included at the end of most chapters, expand the boundaries of classical thermodynamics into other areas of interest and everyday applications, including the following topics: "Thermodynamic Aspects of Biological Systems," "Refrigeration and Freezing of Foods," "Second-Law Aspects of Daily Life," "Saving Fuel and Money by Driving Sensibly," "Thermoelectric Power Generation and Refrigeration Systems," and "Chemical Potential and the Separation Work of Mixtures."
Nearly 2,000 class-tested problems, including design, computer, essay, and labs, provide an opportunity for review and application of the concepts.
Numerous worked examples with sketches, step-by-step procedures, and process diagrams apply concepts to problems in a consistent manner.
De-emphasized use of a formal sign convention for heat and work promotes a clearer understanding of the basic principles.
Environmental consciousness is raised through new problems dealing with energy conservation and conversion and the emission of pollutants and greenhouse gases into the atmosphere.
Over 200 “multiple-choice” problems are given at the end of the chapters.
