Air enters the compressor of a cold air-standard Brayton cycle with regeneration at 100 kPa, 300 K with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10 and the turbine inlet temperature is 1400 K. The turbine and compressor each have isentropic efficiencies of 80% and the regenerator effectiveness is 80%. For k=1.4 calculate the: 4.1 Thermal efficiency for the cycle 4.2 Back work ratio 4.3 Net power 4.4 Rate of exergy destruction in the regenerator for to =300K (6) (6) (4) (4) [20] Air enters the compressor of a cold air-standard Brayton cycle with regeneration at 100 kPa, 300 K with a mass flow rate of 6 kg/s.
