A refrigerator compressor receives R-134a at a rate of 0.08 kg/s at -10 C, 150 kPa and delivers it at 1000 kPa, , 50 C. The input power to the compressor is 3.5 kW. The compressor is cooled with atmospheric air coming in at 25 C and leaving at 32 C. Determine the mass flow rate of air Take the air as an ideal gas with constant specific heat Cpair . That is h4-h3 = Cpair (T4-T3)
