TE 303 - HW #8, P5 - Entropy Balance for a Power Plant - 25 pts

The figure to the right shows a simple vapor power plant operating at steady state with water as the working fluid. Data at key locations are given in the figure. The mass flow rate of the water circulating through the components is 109 kg/s. Stray heat transfer and kinetic and potential energy effects can be ignored.



Determine the following:

a.) The mass flow rate of the cooling water, in kg/s.
b.) The thermal efficiency.
c.) The rates of entropy production, each in kW/K, for the turbine, condenser, and pump.

In your analysis section, place the components in rank order, beginning with the component contributing most to inefficient operation of the overall system.
