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 0C. Determine the power produced by this
engine and its thermal efficiency. Use constant specific heats
at room temperature.
