Steam enters a turbine operating at steady state at 500 lbf/in.2, 600°F, and exits as saturated vapor at 2 lbf/in.2. The power developed by the turbine is 2.5×106 Btu/h and the steam flow rate is 15,000 lb/h. Heat transfer occurs at a location on the surface of the turbine where the average temperature is 300°F. Neglecting kinetic and potential energy effects
a. Determine heat transfer rate, in Btu/h.
b. Determine the rate of entropy production, in Btu/h°R.
c. Draw a T-s diagram.
