Question

An air refrigeration cycle has pressure ratio of 8, temperature of air at beginning of compression is –30ºC and air is cooled up to 27ºC after compression. Compression and expansion processes have isentropic efficiency of 85% and 90% respectively. Consider Cp = 1.005 kJ/kg ·K, γ = 1.4 and air flow rate of 1 kg/s. Determine
