3.47 A closed, rigid tank contains Refrigerant 134a, initially at 100C. The refrigerant is cooled until it becomes saturated vapor at 20C. For the refrigerant, determine the initial and final pressures, each in bar, and the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored. 3.47 A closed, rigid tank contains Refrigerant 134a, initially at 100C. The refrigerant is cooled until it becomes saturated vapor at 20C.
