A “Cold Air-Standard Brayton cycle” gas-turbine power plant delivers a net power output of 60 MW to an electric generator. The compressor intake temperature is 300 K and the maximum temperature in the cycle is 1200 K. The minimum pressure in the cycle is fixed at 100 kPa. If compressor pressure ratio is set at 11 to 1, calculate the plant efficiency and the power output of the turbine. What are the heat addition rate in the combuster and the fraction of the turbine output is required to drive the compressor?
