Question:

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 the turbine is 2. Air (use the IG model) enters each stage of the compressor at 310 K and each stage of the turbine at 1100 K. Determine
(a) The thermal efficiency (ηth) of the cycle and
(b) Back work ratio. Use the IG model.
