Question

Air enters the compressor of a gas turbine at a pressure of 100 kPa and a temperature of 300 K, where it is compressed to a temperature of 680 K. The pressure ratio of the cycle is 8. Before entering the turbine, there is a heat transfer of 950 kJ/kg to the air. Since the turbine's isentropic efficiency is 84 percent,
a) Show the cycle in the T-s diagram.
b) The ratio of the work required to operate the compressor to the work obtained from the turbine.
c) Calculate the thermal efficiency.
