Steam enters the condenser of a vapor power plant at 0.60 bar with a quality of 0.90 and condensate exits at 0.60 bar and 33°C. Cooling water enters the condenser in a separate stream as a liquid at 24°C and exits as a liquid at 36°C with no change in pressure. Heat transfer from the outside of the condenser and changes in the kinetic and potential energies of the flowing streams can be ignored. For steady-state operation, determine the energy transfer from the condensing steam to the cooling water, in kJ per kg of steam passing through the condenser. Select one: a. -2900.16 kJ/kg b. -2105.36 kJ/kg c. -2285.81 kJ/kg d. 2276.70 kJ/kg
