Air enters the compressor of an ideal air standard Brayton cycle at 100 kPa and 290 K with a mass flow rate (m⋅) of 6 kg/s. The compressor pressure ratio is 10. The turbine inlet temperature is 1500 K. If a regenerator with an effectiveness of 70% is incorporated in the cycle, determine (a) the thermal efficiency (ηth,Brayton) of the cycle. Use the PG model for air. (b) What-if Scenario: What would the thermal efficiency be if the regenerator effectiveness increased to 90% ?
