Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c = 4185 J/kgK, Tsat = 355 K, hfg = 2304 kJ/kg.
