3. A refrigerator uses refrigerant-134a as its working fluid and operates on the ideal vapor- compression refrigeration cycle. The refrigerant evaporates at 5°F and condenses at 180 psia. This unit serves a 42,500 Btu/h cooling load. Determine the mass flow rate of the refrigerant and the power that this unit will require.
