A gas turbine power plant operates on a simple Brayton cycle with air as the working fluid. The air enters the turbine at 1 MPa and 1000 K and leaves at 125 kPa, 610 K. Heat is rejected to the surroundings at a rate of 8000 kW and the airflow rate is 25 kg/s. Assuming a compressor efficiency of 80%, determine (a) the net power output. Use the PG model for air. (b) What-if Scenario: What would the net power output be if the compressor efficiency dropped to 75%?
