a) A freezer working on an ideal vapour-compression refrigeration cycle uses refrigerant R- 134a with a mass flow rate of 0.10 kg/s. The refrigerant leaves the evaporator as saturated vapour at a temperature of -8 °C. It leaves the condenser as saturated liquid at a pressure of 0.8 MPa. Determine the power required to drive the compressor. Note that the thermodynamic properties of R-134a are attached at the end of the paper. 0.8 MPa A Figure Q4 -8°C
