With plenty of illustrations and examples, this new edition engages students and makes learning the key concepts of thermodynamics both more accessible and enjoyable. Thermodynamics: An Engineering Approach also promotes a clearer understanding of the basic principles with its focus on a physical, intuitive approach rather than a heavily mathematical one.

New to This Edition:
-De-emphasized use of a formal sign convention for heat and work promotes a clearer understanding of the basic principles.
-Engineering Equation Solver (EES) is an all-new software program that allows students to solve design problems and ask "what if" questions. This program includes a user-friendly equation solver and enables the student to perform parametric and optimization studies and display the results in tabular and graphical forms. Most of the property data needed for solving thermodynamic problems are provided. The program also allows the user to input property data or functional relationships. The EES engine is available at a special discount to those who adopt the text with the Problems Disk.
-Engineering Equation Solver Software Problems Disk has on-line help and contains EES programs that have been developed to solve some of the problems in the book. These programs help students master important concepts without the calculational burden previously required.
-More structured examples now include identification of systems, stated observations, and justifications for assumptions.
-Many new examples and problems, especially those related to design, have been added.
-Economic consciousness is raised through new problems dealing with thermoeconomics and the value of energy conservation.
-Environmental consciousness is raised through new problems dealing with energy conservation and conversion and the emission of pollutants and greenhouse gases into the atmosphere.
-In response to the international treaties banning the use of the refrigerant---12 because of its destructive effect on the ozone layer, the problems and examples in this new edition have been replaced by those dealing with refrigerant---134a.
-Coverage of recent events, such as the new generation of gas turbines with remarkable efficiencies, helps keep students abreast of the latest developments in the field of thermodynamics.

Features:
-More than 1,000 engaging illustrations help students visualize concepts.
-Numerous worked examples with sketches and process diagrams illustrate the geometry and the type of process used and help students relate material to their everyday lives.
-Nearly 2,000 class-tested problems, including design, computer, essay, and labs, provide an opportunity for review and application of the concepts.
-Both the SI and English units of measurement are included, with an emphasis on SI. The problems repeated in different systems are now deleted.
