Using EES (or other) software, study the effects of compressor and turbine isentropic efficiencies as they are

Question:

Using EES (or other) software, study the effects of compressor and turbine isentropic efficiencies as they are varied from 70 to 100 percent on the rate of refrigeration, the net power input, and the COP. Plot the T-s diagram of the cycle for the isentropic case.
Repeat Prob. 11-70 for a compressor isentropic efficiency of 80 percent and a turbine isentropic efficiency of 85 percent.
