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.

Data from 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.
