Alarge condenser(heatexchanger)in a powe rplant must transfer a total of 100 MW from steam run- ning in a pipe to seawater being pumped through the heat exchanger. Assume that the wall separating the steam and seawater is 4 mm of steel, with con- ductivity of 15 W/m K, and that a maximum 5oC difference between the two fluids is allowed in the design. Find the required minimum area for the heat transfer, neglecting any convective heat transfer in the flows.
