Using a classical viewpoint, this Second Edition offers a comprehensive treatment of engineering thermodynamics in order to provide a sound basis for subsequent courses in heat transfer and fluid mechanics and to prepare students to use thermodynamics in professional practice. New features include more than 1300 end–of–chapter problems ranging from confidence–building exercises to more challenging issues that may involve systems with several components, including numerous problems requiring the use of a computer; over 100 design and open–ended problems which are intended as brief design experiences affording students opportunities to develop their engineering judgment and creativity; the International Temperature Scale and refrigerant material; plus interactive software designed to reinforce important ideas and hone students′ problem–solving skills.
