SP40: A gas turbine power plant operates on the Brayton cycle between pressure limits of 100 and 1200 kPa. The working fluid is air, which enters the compressor at 30 C at a rate of 150 m 3 /min and leaves the turbine at 500 C. Using variable specific heats for air and assuming a compressor isentropic efficiency of 82% and a turbine isentropic efficiency of 88%, determine a) the net power output in kW, b) the back work ratio, and c) the thermal efficiency....
