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°C at a rate of 1100 m3/min and leaves the turbine at 650°C. Assume a compressor isentropic efficiency of 85 percent and a turbine isentropic efficiency of 88 percent. Use constant specific heats with cv = 0.821 kJ/ kg·K, cp = 1.108 kJ/kg·K, and k = 1.35.
