Air enters the compressor of a cold-air-standard Brayton cycle with regeneration, intercooling and reheating at 100kPa, 300K, with a mass flow rate of 6kg/s. The compressor pressure ratio are the same across each compressor stage. Overall compression ratio of the system is 10. The intercooler and reheater both operate at the same pressure. The temperature at the inlet to the second compressor stage is 300K. The temperature at the inlet of both turbine is 1400K. The compressor and turbine stages each have isentropic efficiencies of 80% and the regenerator effectiveness is 80%. For k=1.4, calculate: A) the thermal efficiency of the cycle, the back work ratioand the net power developed, in kW.
