4.51 Steam at 1800 lbf/in.2 and 11008F enters a turbine operating at steady state. As shown in Fig. P4.51, 20% of the entering mass flow is extracted at 600 lbf/in.2 and 5008F. The rest of the steam exits as a saturated vapor at 1 lbf/in.2 The turbine develops a power output of 6.8 3 106 Btu/h. Heat transfer from the turbine to the surroundings occurs at a rate of 5 3 104 Btu/h. Neglecting kinetic and potential energy effects, determine the mass flow rate of the steam entering the turbine, in lb/s.

inlet is 3 m higher than at the exit. Heat transfer from the turbine to its surroundings occurs at a rate of 1.1 kJ per kg of steam flowing. Let g 5 9.81 m/s2. Determine the power developed by the turbine, in kW.
