Find the flows and fluxes of exergy in the condenser of Problem 9.29. Use them to determine the second law efficiency, T0 = 15?C.

Problem 9.29

A coal-fired power plant produces 25 kg/s steam at 3 MPa, 600?C in the boiler. It cools the condenser with ocean water coming in at 15?C and returned at 18?C, so the condenser exit is at 50?C. Find the net power output and the required mass flow rate of ocean water.
