The centrifugal air compressor of a gas turbine receives air from the ambient atmosphere where the pressure is 1 bar and the temperature is 300oK. At the discharge of the compressor the pressure is 4 bar, the temperature is 480 oK and the velocity is 100 m/sec. The mass flowrate into the compressor is 15 kg/sec. Assuming steady flow determine the power required to drive the compressor
