9-99 A gas turbine for an automobile is designed with a regenerator. Air enters the compressor of this engine at 100 kPa and 30°C. The compressor pressure ratio is 10; the maximum cycle temperature is 800°C; and the cold air stream leaves the regenerator 10°C cooler than the hot air stream at the inlet of the regenerator. Assuming both the compressor and the tur- bine to be isentropic, determine the rates of heat addition and rejection for this cycle when it produces 115 kW. Use con- stant specific heats at room temperature. Answers: 258 kW, 143 kW
