An aircraft engine operates on a simple ideal Brayton cycle with a pressure ratio of 11.5. Heat is added to the cycle at a rate of 500 kW, air passes through the engine at a rate of 1 kg/s, and the air at the beginning of the compression is at 70 kPa and 0°C. Determine the power produced by this engine and its thermal efficiency. Use constant specific heats at room temperature. The properties of air at room temperature are cp = 1.005 kJ/kg-K and k = 1.4. The power produced by this engine is The thermal efficiency of this engine is KW. %.
