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

a) Thermal efficiency for the cycle
b) Back work ratio
c) Net power
d) Rate of exergy destruction in the regenerator for t0=300K
