A gas turbine power plant operates on a simple Brayton cycle with air as the working fluid. Air enters the turbine at 800 kPa and 1200 K, and it leaves the turbine at 100 kPa and 750 K. Heat is rejected to the surroundings at a rate of 6800 kW, and air flows through the cycle at a rate of 20 kg/s. Assuming a compressor efficiency of 80%, determine
Net power output (W⋅ net) of the plant. Use the PG model.
