Air enters the compressor of a gas turbine plant at ambient conditions of 100 kPa and 25 degrees C with a low velocity and exits at 1 MPa and 347 degrees C with a velocity of 90m/s. the compressor is cooled at a rate of 1500 kJ/min and the power input to the compressor is 250 kW.
Determine the mass flow rate of air through the compressor.
