Steam enters a turbine operating at steady state at 700oF and 450 lbf/in2 and leaves as a saturated vapor at 0.8 lbf/in2. The turbine develops 12,000 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 2 x 106 Btu/h. Neglect kinetic and potential energy changes from inlet to exit. Determine the exit temperature, in oF, and the volumetric flow rate of the steam at the inlet, in ft3/s.

Problem 1: This is textbook problem 4.51 (page 224) Steam at 1800 lbf/in2 and 1100 °F enters a turbine operating at steady state. As shown in the Figure, 20% of the entering mass flow is extracted at 600 lbf/in2 and 500 °F. The rest of the steam exits as a saturated vapor at 1 lbf/in2 . The turbine develops a power output of 6.8×106 Btu/h. Heat transfer from the turbine to the surroundings occurs at a rate of 5×104 Btu/h....
