Reconsider Prob. 739. Using EES (or other) software, evaluate and plot the work done by the refrigerant

Question:

Reconsider Prob. 7–39. Using EES (or other) software, evaluate and plot the work done by the refrigerant as a function of final pressure as it varies from 0.8 to 0.4 MPa. Compare the work done for this process to one for which the temperature is constant over the same pressure range. Discuss your results.
