Written in an informal, first-person writing style that makes abstract concepts easier to understand, PRINCIPLES OF ENGINEERING THERMODYNAMICS transforms the way students learn thermodynamics. While continuing to provide strong coverage of fundamental principles and applications, the book asks students to explore how changes in a particular parameter can change a device's or process' performance. This approach helps them develop a better understanding of how to apply thermodynamics in their future careers and a stronger intuitive feel for how the different components of thermodynamics are interrelated. Throughout the book, students are encouraged to develop computer-based models of devices, processes, and cycles and to take advantage of the speed of Internet-based programs and computer apps to find thermodynamic data, just as practicing engineers do.
