An ideal vapor-compression refrigeration cycle operates at a steady state with refrigerant R-134a as the working fluid. The saturated vapor enters the compressor at -5C, and the saturated liquid leaves the condenser at 35 C . The mass flow rate (m) of refrigerant is 5.0 kg/min .

a) Determine the compressor power (Wnet).

b) Determine the refrigeration capacity

c) Determine the Coefficient of Performance (COPr)
