Question: air enters the compressor of a cold airstandard brayton cycle...

Question details

Air enters the compressor of a cold air-standard Brayton cycle with regeneration, intercooling, and reheat at 100 kPa, 25°C, with a net power output of 1.35 MW. The compressor pressure ratio is 12, and the pressure ratio across the first compressor stage is 4. The intercooler and reheater both operate at the same pressure. The temperature at the inlet to the second compressor stage is 45°C, and the inlet temperature for each turbine stage is 1400 K The compressor and turbine stages each have isentropic efficiencies of 82% and 84% respectively. The regenerator effectiveness is 78%. You may assume the specific heats are constant (k=1.4). Determine the back work ratio (total compressor work / total turbine work)
