Steam enters a turbine at an enthalpy of 3300kJ/kg and a velocity of 180 m/s. The steam comes out of turbine at an enthalpy of 2700 kJ/kg with a velocity of 120 m/s. At the condition of steady state, the turbine develops work equal to 550 kJ/kg of steam flowing through the turbine. The heat transfer between the turbine and its surroundings occurs at an average temperature of 370 K. The entropy of steam at inlet and exit of turbine are 6.932 kJ/kg-K and 7.361 kJ/kg-K, respectively. Neglecting the changes in potential energy between inlet and outlet, work out the following:
(i) Sketch the system and show the process on p-v and h-s diagrams
(ii) Calculate the rate at which entropy is produced within the turbine per kg of steam flowing.
