An aircraft engine operates on a simple ideal brayton cycle with a pressure ratio of 10. 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. (241 kw; 0.482)
