Question: Repeat 10-2-5 [OVE] if the compressor and turbine have an isentropic efficiency of 80%. Problem 10-2-5 Air enters the compressor of an ideal Brayton refrigeration

Repeat 10-2-5 [OVE] if the compressor and turbine have an isentropic efficiency of 80%.
Problem 10-2-5
Air enters the compressor of an ideal Brayton refrigeration cycle at 200 kPa, 270 K, with a volumetric flow rate of 1 m3/s, and is compressed to 600 kPa. The temperature at the turbine inlet is 330 K. Treating air as a perfect gas, determine
(a) The refrigeration capacity in kW and tons and
(b) The net power input in kW,
(c) The coefficient of performance (COPR).
