A vapor compression cycle uses R134a as the refrigerant. The vapor condenses at 40°C and is subcooled to 35°C before entering the expansion valve. The evaporating temperature is í5°C. The vapor leaving the evaporator is superheated to 5°C at entry to the compressor. The heat absorption rate is 13 kW and the compression process is isentropic. Calculate (i) the refrigerant flow rate, (ii) the work input, and (iii) the COP
