Air enters the compressor of an ideal Brayton refrigeration cycle at 100 kPa,
270 K. The compressor pressure ratio is 3, and the temperature at the turbine
inlet is 310 K. Considering the compressor and turbine have isentropic
efficiencies of 80 and 88%, respectively, please determine:
(a) the net work input, per unit mass of air flow, in kJ/kg.
(b) the refrigeration capacity, per unit mass of air flow, in kJ/kg.
(c) the coefficient of performance.
