Air enters the compressor of a gas-turbine plant at ambient conditions of 100 kPa and 25°C with a low velocity and exits at 1 MPa and 347°C with a velocity of 90 m/s. The compressor is cooled at a rate of 1500 kJ/min, and the power input to the compressor is 250 kW. Determine (a) temperature at the compressor exit Investigate the effect of cooling rate from 1300 kJ/min to 1600 kJ/min in steps of 50 kJ/min on the mass flow and exit temperature.
