QUESTION 1 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. By using variable specific heats, analyse the back work ratio and compare the thermal efficiency of the cycle for these two cases: i. no regenerator is used ii. a regenerator is used with 75 percent effectiveness [13 marks] [12 marks] [Total: 25 marks]
