Engineering Thermodynamics — Pk Nag
Each chapter ends with hundreds of unsolved problems, categorized as:
Start with the easier end-of-chapter problems. Then move to the tougher ones. The book is structured so problems increase in difficulty. pk nag engineering thermodynamics
Before analyzing the book, it is essential to understand the author. (Ph.D., IIT Kharagpur) was a distinguished academician and researcher. He served as a professor at the Indian Institute of Technology (IIT) Kharagpur, one of India’s premier institutes. His deep understanding of thermodynamics, coupled with his ability to simplify complex concepts, made him an iconic figure. His passing in 2015 left a void, but his legacy continues through his books, of which Engineering Thermodynamics remains the flagship title. Each chapter ends with hundreds of unsolved problems,
The final section deals with real-world engineering: Before analyzing the book, it is essential to
One of the most confusing aspects for beginners is the concept of "path function" versus "point function." Nag’s treatment of Work and Heat is distinct. He uses graphical representations (P-V diagrams) extensively to show that work is not a property, but an interaction. The dissection of different types of work—shaft work, electrical work, and paddle wheel work—is thorough and often the source of excellent numerical problems.
Here, the book begins to shine in its derivations. The First Law is not just presented as an energy balance equation ($Q - W = \Delta E$); it is derived for a closed system and then extended to open systems.
