An ideal gas is taken through a cyclic thermodynamic process through four steps. The amounts of heat involved in these steps are `Q_1=5960J`, `Q_2=-5585J`, `Q_3=-2980J` and `Q_4=3645J` respectively. The corresponding quantities of work involved are `W_1=2200J`, `W_2=-825J`, `W_3=-1100J` and `W_4` respectively.
(a) Find the value of `W_4`.
(b) What are the efficiency of the cycle?

Text Solution

Verified by Experts

The correct Answer is:
`(i) Delta Q _(r), = Delta W _(r)` in cyclic process (ii) `eta = (Delta W r)/(DeltaQ("only the ")) xx 100`
