Required Informetion 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. Assume an efficiency of 86 percent for each compressor stage and an efficiency of 90 percent for each turbine stage. Use variable specific heats. Determine the back work ratio and the thermal efficiency of the cycle, assuming a regenerator with 78 percent effectiveness is used. The back work ratio is % The thermal efficiency is %
