PROBLEM #2 (68 pts.) Steam at 200 psia, 600°F (State 1) enters an adiabatic turbine cperating at steady state with a mass flow rate of 16.5 lbm/min and exits at 15 psia, 240°F (State 2), Neglecting the changes in kinetic and potential energies and assuming the surroundings to be at T.- 537 R. Determine: a) the actual power output, in Btu/min. b) the reversible (or maximum) power output, in Btu/min. c) the rate of exergy destruction, in Btu/min....

In a steam power plant, water is pressurized in an adiabatic pump from 100kPa as a saturated liquid to 5 MPa at 150C. The pump is directly driven by an adiabatic steam turbine, which also powers a generator. Steam enters the steam turbine at 5 MPa and 450C and leaves as saturated vapor at 100kPa. Determine the net-work output of the pump-turbine-generator combination if the generator operates at 85% efficiency. (in kJ/kg) ) b) Determine the entropy generation for both...

2. Ideal Rankine cycle. The condenser pressure is 4 psia. Steam goes into turbine at 1100F and 1300 psia. The mass flow rate of steam is 2,000,000 lb/h. Cooling water from a lake flows through the condenser at 95,000,000 lb/hr and comes into the condenser at 63F. Determine: a) The net power made (BTU/h) b) Rate of heat transfer in the condenser (BTU/h) c) Overall thermal efficiency (%) d) The outlet temperature of the cooling water (F)
