Q15/ (9-121) Consider an ideal gas-turbine cycle with two stages of compression and two stages of expansion. The pressure ratio across each stage of the compressor and turbine is 3. The air enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Determine the back work ratio and the thermal efficiency of the cycle, assuming: (a) no regenerator is used and (b) a regenerator with 75 percent effectiveness is used. Use variable specific heats.
