Repeat Problem, but use variable specific heats for the air.
Problem
A Brayton power cycle has air, with a mass flow rate of 60 kg/s, entering the compressor at 100 kPa and 25°C. The air exits the compressor at 1300 kPa. The isentropic efficiency of the turbine is 0.80 and the isentropic efficiency of the compressor is 0.75. Consider the air to have constant specific heats. Plot the net power produced by the cycle, the turbine inlet temperature, and the thermal efficiency for the cycle for combustor heat inputs ranging between 5000 kW and 50,000 kW.
