Q1) When R-134a used as a working fluid in a refrigerator, the working fluid at (-10 °C) enters the compressor and leaves at (46 °C), when the condenser temperature is 38 "C, the mass flow rate of the refrigerant is 0.4 kg/s. Find the Indicated and actual COP (when k for R-134a = 1.127 (HFC-R134a)), also find refrigerator capacity and low and high pressures.
