Air enters the compressor of an air-standard brayton cycle with regeneration at 100 kpa and 300 k, with a mass flow rate of 6 kg/s. the compressor pressure ratio is 10 while the turbine inlet temperature is 1400 k. the turbine and compressor each have an isentropic efficiency of 80%, while the regenerator effectiveness is 80%. assuming constant properties evaluated at 300 k determine:

a) the thermal efficiency of the cycle

b) the back-work ratio

c) the net power produced, in kw

d) the rate of entropy generation in the regenerator, in kw/k.
