A vapor compression refrigeration cycle operates at steady flow conditions with 0.25 kg/s or R-134a. The table below shows some of the operating parameters and properties for the refrigerant. The compressor is refrigerated, and the condenser is also cooled with water. The compressor receives shaft power equivalent to 7.5 hp. Neglecting changes in kinetic and potential energy changes and any heat loss between devices, please answer the following.
