Question 3 25 pts Steam at 60 Bar and 400C enters a well-insulated turbine at steady-state and expands to 0.5 bar. The mass flow rate is 1.5 kg/s. The kinetic and potential energy changes are negligible. (i) Sketch a T-s diagram for the process showing isentropic and actual process. (6 points) (ii) If turbine efficiency is 90%, determine the power developed by the turbine, in kW. (19 points) (Similar to "Turbine entropy-example")
