Thermodynamics Questions

---------------------------------------------------

Dear friends while going through gate paper of this year, I came across one problem which many of my students find difficult to solve, the problem was of Vapour compression cycle but when you look critically the problem it can't be solved without applying thermodynamics to it. So you can see how deceptive sometimes the problem can be.

Lets look the problem first:

Now let us see how to solve this problem:

so you see how important thermodynamics is. If you know thermodynamics then RAC, Power plant and Heat transfer will become cake walk for you all.

Few more problems from same set:

Now solutions of above problems:

Now few problems from set 2(you can see the problems in IISC Gate site)

Few problems from set 1:

Now solutions of above problems:

Prepare well 

All the Best
