A gas turbine at ground level draws air at 300 K and 100kPa. It operates at a pressure ratio of 12. The temperature at the turbine exit is found to be 1400 K. Given that the turbine and the compressor have isentropic efficiencies of 0.85 and 0.85 respectively, calculate the following: Ignore any pressure drop between the compressor exit and the turbine inlet. Assume a y of 1.4.. a) Draw a T-s diagram of the gas turbine cycle [5 marks] b) Calculate the temperature at the compressor exit. [5 marks] c) Also, calculate the temperature at the turbine exit. [5 marks] d) Using the above, calculate the compressor work, turbine work and the cycle efficiency. [5 marks] e) If the waste heat of this turbine is to be used to run a secondary expansion cycle, what is the maximum cycle efficiency that can be obtained from that heat recovery cycle?
