Refrigerant-134a enters the condenser of a residential heat pumpat 900 kPa and 65oC at a rate of 0.018 kg/s and leavesat 750 kPa subcooled by 2oC. The refrigerant enters thecompressor at 200 kPa superheated by 3oC. Determine (a)the isentropic efficiency of the compressor in decimal (up to twodecimals), (b) the rate of heat supplied to the heated room, and(c) the COP of the heat pump. Also determine (d) the COP if thisheat pump operated on the ideal vapour compression cycle betweenthe pressure limits of 200 and 900 kPa
