9-90 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 850 m³/min and leaves the turbine at 650°C. Using variable specific heats 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, and (c) the thermal efficiency. Answers: (a) 6081 kW, (b) 0.536, (c) 37.4 percent (2) 1.6 MPa Compressor 1100 kPa 40°C FIGURE P9-90 Combustion chamber 3 Turbine 650°C (4) W net S d C C ( A
