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. (Ignore the variation of specific heats for air with temperature
