A Brayton cycle using air receives the air into the compressor at 1 atm and 70°F. The air exits the compressor at 11 atm and has a mass flow rate of 75 lbm/s. The isentropic efficiency of the turbine is 0.80, and the isentropic efficiency of the compressor is 0.78. Consider the air to have variable specific heats. Plot the net power produced by the cycle and the thermal efficiency for the cycle for turbine inlet temperatures ranging between 1500°F and 2500°F.
