Air enters a compressor at a temperature of 100 kPa and 25°C and leaves the compressor at a temperature of 277°C and a speed of 75 m/s.1350 kj/min heat loss occurs from the compressor to the ambient environment. Since the power required for the compressor is 210 kW, determine the compressor's flow rate.(Note: the potential energy change is negligible.)
