Question: Repeat Problem 9.46 using turbine and compressor efficiencies of 0.85 and 75%, respectively. Air enters the regenerative Brayton cycle of Fig. 9.47 cycle at 14

Repeat Problem 9.46 using turbine and compressor efficiencies of 0.85 and 75%, respectively.
Air enters the regenerative Brayton cycle of Fig. 9.47 cycle at 14 psia and 20°F. The pressure ratio is 4 and the maximum temperature is 1800ºF. Assuming an ideal cycle with constant specific heats, calculate the cycle efficiency and the back-work ratio. Compare with the results of Problem 9.41 if that problem was previously assigned.
