Question: Consider an ideal gas refrigeration cycle using helium as the working fluid. Helium enters the compressor at 100 kPa and 17oC and compressed to 400

Consider an ideal gas refrigeration cycle using helium as the working fluid. Helium enters the compressor at 100 kPa and 17oC and compressed to 400 kPa. Helium is then cooled to 20oC before it enters the turbine. For a mass flow rate of 0.2 kg/s, the net power input required is
(a) 28.3 kW
(b) 40.5 kW
(c) 64.7 kW
(d) 93.7 kW
