A gas turbine operating a simple Brayton cycle operates between lower and upper temperatures of 303K and 1400K respectively. The pressure ratio of the cycle is 9 and both the compressor and turbine have isentropic efficiencies of 0.85. Using the cold air standard, determine the following: a) The temperature at the end of the compression process and expansion processes [8 marks] b) The amount of heat energy input required per kg of air [3 marks) c) The maximum possible thermal efficiency of the cycle [3 marks] d) The thermal efficiency of the actual cycle [6 marks) e) The mass flow rate required to achieve a net power output of 5.5 MW [5 marks] Total 25 marks
