Agas-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 at a rate of 850 m^3/min and leaves the turbine at 650 degrees celsius. using constant specific heats at room temperature for air and assuming a compressor isentropic efficiency of 85 percent and a turbine isentropic efficiency of 88 percent, determine: a) the net power output b) the back work ratio c) the thermal efficiency d) the brayton cycle efficiency
