Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 35 degrees C at a rate of 0.018 kg/s and leaves at 800 kPa as a saturated liquid. If the compressor consumes 1.2 kW of power, determine (a) the COP of the heat pump and (b) the rate of heat absorption from the outside air.

P1=800 kPa P2=800 kPa mass flowrate=0.018 kg/s
