Using R134a as the working fluid and the operating conditions below. Consider the rig without a regenerator (state 7) where the flow goes directly from the compressor (state 1) to heat exchanger 3 (state 4), then calculate the following:

thermal efficiency of the cycle
net power output
rate of heat transfer to the refrigerant in every heat exchanger
rate of heat transfer from refrigerant to the cooling water in the condenser
the mass flow rate of cooling water in the condenser

T_{turbine inlet} (^oC) = 170

P_{heat exchange}(bar) = 35

P_condenser (bar) = 10

η_turbine(%) = 72

Mass Flow Rate_refrigerator(kg/s) = 78

η_compressor(%) = 0.15

T_{w, condition in}(^oC) = 10

T_{w, condition out}(^oC) = 20
