. Air enters the compressor of an ideal gas refrigeration cycleat 7oC and 40 kPa and the turbine at 37oC and 170 kPa. The massflow rate of air through the cycle is 0.3 kg/sec. Assuming variablespecific heats for air, determine (a) the rate of refrigeration,(b) the net power input, and (c) the coefficient of performance.Also, draw the T-s diagram of the gas refrigeration cycle.
