5 Lbm of Refrigerant 22 (R-22) is contained in a piston cylinder device. The R-22, initially at a pressure of 30 psia and a volume of 4 ft^3, is heated at constant pressure until the temperature is 70 degrees F. The heat transfer is from a source at 80 degrees F. What is the total entropy generation for this process?
