Air enters the compressor of a cold air-standard brayton cycle with regeneration, intercooling, and reheat at 100 kpa, 300 k, with a mass flow rate of 6 kg/s. the compressor overall pressure ratio is 10, and the pressure ratios are the same across each compressor stage. the intercooler and reheater both operate at the same pressure. the temperature at the inlet to the second compressor stage is 300 k, and the inlet temperature for each turbine stage is 1400 k. the compressor and turbine stages each have isentropic efficiencies of 80% and the regenerator effectiveness is 80%. for k = 1.4 & cp = 1.005 kj/kg. k, calculate (a) the thermal efficiency of the cycle. (b)the back work ratio. (c) the net power developed, in kw.
