Exhaust steam from a steam power plant in Batangas is at 7 kPa(29°C) at the rate of 75 kg/s enters a single pass condenser containing 5,780 pcs copper tubes with a total surface area of 2950 m2. The steam has a moisture content of 10% (hf = 163.4 kJ/kg & hfg = 2572.5 kJ/kg) and the condensate leaves saturated liquid at steam temperature. The cooling water flow rate is 4.413 m3/s entering at 20°C. Size of tubes, 25 mm O.D. by 3 mm thick wall. Find the overall heat transfer coefficient.
