Water enters the condenser of surface type; the temperatures of the water that is used to cool the steam is 17oC and 28oC respectively. The pressure of the condenser is at 0.055 bar and 0.87 dry fraction. The overall heat transfer coefficient in the condenser is 3 kW/m2.oC. The condenser has three passes and tubes used have 17.6 mm internal diameter and 20 mm external diameter. If the flow area is 1.3 m2, Design the condenser. If the condenser is used to condense 240 tons of steam per hour.
