Question:

The gas turbine power plant described in problem, 8-1-35[BCQ], is converted into a multi-stage cycle with two stages of compression and two stages of expansion. The pressure ratio across each stage of the compressor and the turbine is 2. Using the Gas Turbine Simulator RIA, plot how thermal efficiency (ηth,Brayton) varies with first compressor efficiency varying from 70% to 90%.
