Question: An aircraft engine operates on a simple ideal Braytoncycle with a pressure ratio of 9. Heat is added to the cycleat a rate of 500

An aircraft engine operates on a simple ideal Braytoncycle with a pressure ratio of 9. Heat is added to the cycleat a rate of 500 kW,air passes through the engine at a rate of1 kg/s,and the air at the beginning of the compression is at70 kPa and 0C. Determine the power produced by this engineand its thermal efficiency. Use constant specific heats at roomtemperature.The properties of air at room temperature are c_p = 1.005 kJ/kgK and k = 1.4.

The power produced by this engine is __ kW.

The thermal efficiency of this engine is __ %.
