Consider an ideal gas-turbine cycle with two stagesof compression and two stages of expansion. The pressureratio across each stage of the compressor and turbine is 3.The air enters each stage of the compressor at 300 K and eachstage of the turbine at 1200 K. Assume an efficiency of86 percent for each compressor stage and an efficiency of 90percent for each turbine stage. Use variable-specific heats.Determine the back-work ratio and the thermal efficiency of thecycle.
a. no regenerator is used.
b. a regenerator with 75 percent effectiveness isused.
