Written in an informal, first-person writing style that makes abstract concepts easier to understand, PRINCIPLES OF ENGINEERING THERMODYNAMICS promises to transform 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's 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.
- Well-placed and practical examples in every chapter help students understand the use of thermodynamics in solving engineering problems.
- The author uses a methodical approach (clear explanations, real world examples, and a wealth of exercises) to help students learn a process for solving problems.
- Software is used to develop graphs and show trends, helping students develop engineering judgment.
- The book is software-neutral so students can use any package they are familiar with (for example, MATLAB or Mathcad).
- Steam tables are included in the appendix, but the emphasis is on using software to solve thermodynamic problems.

"...the author's strength is his informal, first-person writing style. It is an easy read for students."
"Nice presentation pace, and the examples are well placed and numerous."
"I really like the methodical approach teaching the student to use a "process" for solving the problems. I really like how you use the software to develop graphs and show trends. This develops the engineering judgment that we desire for our students to have."
"Good use of practical examples overall. Good flow from one topic to another. I really like the clarity of the writing. Overall, the easiest-to-read Thermo text that I have seen."
"The nature of topics is well presented with concepts from one chapter as a building block for the concepts in the following chapter. The author has provided many practical examples to illustrate the theory. The material is well written and up to the point."
