Now in its Eighth Edition, Principles of Engineering Thermodynamics continues to set the standard for teaching readers how to be effective problem solvers, emphasizing the authors' signature methodologies that have taught over a half million students worldwide. This new edition provides a student-friendly approach that emphasizes the relevance of thermodynamics principles to some of the most critical issues of today and coming decades, including a wealth of integrated coverage of energy and the environment, biomedical/bioengineering, as well as emerging technologies. Visualization skills are developed and basic principles demonstrated through a complete set of animations that have been interwoven throughout. This edition also introduces co-authors Daisie Boettner and Margaret Bailey, who bring their rich backgrounds of success in teaching and research in thermodynamics to the text.
