A R-12 heat pump cycle shown in Fig. P6.71 has a R-12 flow rate of 0.05 kg/s

Question:

A R-12 heat pump cycle shown in Fig. P6.71 has a R-12 flow rate of 0.05 kg/s with 4 kW into the compressor. The following data are given
State 1 2 3 4 5 6
P kPa 1250 1230 1200 320 300 290
T °C 120 110 45 0 5
h kJ/kg 260 253 79.7 - 188 191
Calculate the heat transfer from the compressor, the heat transfer from the R-12 in the condenser and the heat transfer to the R-12 in the evaporator.
