Refrigerant R-22 is the working fluid in a Carnot vapor refrigeration cycle for which the evaporator temperature is 0°C. Saturated vapor enters the condenser at 40°C, and saturated liquid exits at the same temperature. The mass flow rate of refrigerant is 4 kg/min. Determine
(a) The rate of heat transfer (QC) to the refrigerant passing through the evaporator,
(b) The coefficient of performance (COPR).
(c) The net power input (Wnet) (magnitude only) to the cycle in kW and
