Single pass surface condenser is to handle 5100 kg/h of dry and saturated steam at 50°C. The outer and inner diameters of the tubes are 20 mm and 17 mm, respectively. The length of the tube is 3 m. The cooling water enters the tube at 20°C. The velocity of water through the tube is 2 m/s and the temperature rise of the cooling water is 10°C. Calculate number of tubes. Take the following data :
