A steam turbine under steady operations (as shown in the figure to the right) has steam entering the inlet of the turbine at 2MPa, 350C and exits the turbine at 100kPa with a quality of 0.85. The turbine also loses 700 kW of heat to the ambient through its casing during actual operations. Mass flow rate of the steam is 3 kg/s. Determine: a) the actual power that this turbine produces. (7 marks) b) maximum possible power output from this turbine with ideal assumptions. (7 marks) c) the second-law efficiency of this turbine. (3 marks) Steam turbine To=25C Po = 100 kPa Hint: Think about when maximum power could be realised from any device. W
