An ideal Brayton cycle refrigeration cycle has a compressor pressure ratio of 6. At the compressor inlet, the pressure and temperature of the entering air are 20 lbf/in2 and 460 R. The temperature at the inlet of the turbine is 700 R. For a refrigerating capacity of 15 tons, determine (a) the mass flow rate in lbm/min. (b) the net power input, in Btu/lbm. (c) the coefficient of performance."
