Concepts taught in class
Student Opinion:-
It is a very interesting course. It's not very hard to understand it's concepts and solve problems. You can practice problems from a number of books like Fox and McDonald, Som and Biswas etc. But you even not need to do problems from books if you get tutorials in the class.
It also serve as a prerequisite for heat transfer course in your 5th semester.
Books:-
1) Fox and McDonald
2) Som and Biswas
3) Kundu and Kohen
4) Cengel and Cimbala
How to Crack the Paper
For exam,firstly you should have confidence in your basic concepts. You should try to complete your tutorials and class problems for a decent practice. For more questions, you can refer above mentioned books. But the exam wouldn't have, generally, hard questions. You just need clarity in your concepts and a decent practice to solve questions in the exam.
