A refrigerator uses refrigerant-134a as its working fluid and operates on the ideal vapor-compression refrigeration cycle. The refrigerant evaporates at 5.00°F and condenses at 180 psia. This unit serves a 45000 Btu/h cooling load. Determine the mass flow rate of the refrigerant and the power that this unit will require. (Take the required values from saturated refrigerant-134a tables.) (Round the final answers to three decimal places.) The mass flow rate of the refrigerant is Ibm/h, and the power requirement is kW.
