A gas turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 and 1600 kPa. The working fluid is air, which enters the compressor at 40 degrees Celsius and leaves at 650 degrees Celsius. Using constant specific heats for air and assuming a compressor isentropic efficiency of 85% and a turbine isentropic efficiency of 88%, determine (a) the net work output, (b) the thermal efficiency. The cut off ratio of the cycle is 2.6. Assume constant specific heats for air at room temperature (Cp=1.005 KJ/kg.K and k=1.4)
