Steam enters a turbine at a pressure of 40 bar and temperature of 513 C with a mass flow rate of 10 kg/s. The exit pressure is at 3.5 bar and temperature of 139 C. Heat loss from the turbine is 350 kW and the ambient is at a pressure of 1 bar and temperature of 27 C. The kinetic and the potential energy can be regarded as negligible. a. Sketch the process in a T-s diagram showing the important points with proper labels Calculate the: (i) actual power output (ii) exergy changes in the process (iii) exergy destroyed (iv) maximum exergy of the steam at the inlet (v) efficiency of the turbine 1
