Concepts taught in class

Basic concepts, work, heat, first and second law of thermodynamics for both control mass and control volume, entropy, irreversibility, availability, gas mixtures, vapour and gas cycles

Student Opinion

In my opinion start studying this course from the beginning itself. It requires heavy to super heavy effort. The concept is relatively easy to understand. The challenge is to solve the questions. Practice solving questions using both EES and the tables. The exam will involve the usage of heavy interpolations. So, dexterity in the usage of calculators is a must.

Lot of new concepts are taught which are practically applicable. This is a very important course.

How to Crack the Paper

Book to refer: Fundamentals of Thermodynamics Slides by prof.S Mitra The above to resources are very good. One needs to put lot of effort in this course.
