Question
**GIVEN:** 1. Water in Rankine cycle. 2. Steam leaves steam generator at 1500 lbf/in² and 1095°F. 3. Because of heat transfer and friction, pressure and temperature at turbine inlet are reduced to 1400 lbf/in² and 1000°F. 4. Pump and turbine have 90% of isentropic efficiencies. 5. Pressure at inlet of condenser = 2 lbf/in². Due to friction, condensate exits condenser at 1.5 lbf/in² and 105°F. 6. Condensate is pumped to 1600 lbf/in² and then enters steam generator. 7. Net power output of whole cycle = 1 x 10⁹ Btu/hour. 8. The cooling water temperature increases from 60°F to 76°F with very little pressure drop as it flows through condenser. **DETERMINE:** 1. Mass flow rate of steam in lb/s. 2. Rate of heat transfer in Btu/s to the working fluid passing through the steam generator. 3. % thermal efficiency. 4. Mass flow rate of cooling water in lb/s.
