Question 1: (28 marks) a) Sketch the p-V and T-s diagram for the above cycle. b) Calculate the thermal efficiency. c) Apply the concept of isentropic process to find the maximum cycle temperature. d) Write a mathematical model for the net-work in terms of temperatures. e) Solve the above model to find the net-work done during the cycle. Take C_p = 0.718 kJ/kg.K; C_v = 1.005 kJ/kg.K; gamma = 1.4. Question 2: (44 marks) Air is compressed from 1 bar and 15Â°C to 9 bars in a Gas-Turbine cycle. The high pressure turbine drives the compressor, whereas the low pressure turbine is coupled with an electrical generator. The compressor and turbine efficiencies are 85% and 75% respectively. Heat is added to the compressed air after leaving the compressor till its temperature reaches 900Â°C. The air then expands in the high pressure turbine to an intermediate pressure and is reheated to 900Â°C before expanding another time in the low pressure turbine to 1 bar. a) Identify the given system and processes on a schematic diagram showing all of the devices in the system and the direction of air flow from one device to another inside the system. b) Sketch T-s diagram and indicate clearly all the processes and states. c) Find the intermediate pressure. d) Determine the turbine work. e) Calculate the back work ratio. f) Formulate the thermal efficiency of the cycle based on the given criteria and express it in terms of temperatures. g) Solve the above expression to find the thermal efficiency of the cycle. Assume 15 kg/s air flow rate, C_p = 1.005 kJ/kg.K.
