a) Steam expands in an adiabatic, reversible turbine from 3.0 MPa, 700 C to a final pressure of 10 kPa. If the flow rate is 1.7 kg/s: i) Show that the power output is - 2500 kW [9 Marks) ii) show the process on a T-s diagram. [4 marks) b) Air with a flow rate of 20 m/s enters a compressor at 100 kPa and 20 C and is compressed to 400 kPa. Assume the process is adiabatic and the compressor has an efficiency of 84%. Calculate: 1) the exit temperature [5 marks) ii) Show that the power input into the compressor is ~ 4060 kW [7 marks]
