Air enters the compressor of an ideal air standard Brayton cycleat 100 kPa and 290 K with a mass flow rate (m⋅)of 6 kg/s. The compressor pressure ratio is 10. The turbine inlettemperature is 1500 K. If a regenerator with an effectiveness of70% is incorporated in the cycle, determine (a) the thermalefficiency (ηth,Brayton) of the cycle. Use thePG model for air. (b) What-if Scenario: What wouldthe thermal efficiency be if the regenerator effectivenessincreased to 90% ?
