A gas turbine for an automobile is designed with a regenerator. Air enters the compressor of this engine at 100kPa and 20oC. The compressor pressure ratio is 88. The maximum cycle temperature is 800oC and the cold air stream leaves the regenerator 10oC cooler than the hot air stream at the inlet of the regenerator.
Assuming both the compressor and the turbine to be isentropic, determine the rates of heat addition and rejection for this cycle when it produces 150kW. Use constant specific heats at room temperature.
Draw a T−s diagram of the engine.
