A single pass condenser with 5/8- inch OD tubes whose effective length is 18 ft and whose thickness is 0.046 inch receives 112,000 lb/hr of steam at 84 °F with an enthalpy of 960 BTU/b. The resulting condensate leaves at 84 °F with little change in kinetic energy. Circulating water enters the tube counter flow at 68°F and leaves at 78 °F. If the heat transfer coefficient is Uo= 630 BTU/HR ft2 0F, find: a) the rate of flow of water, GPM, b) heating surface area, sq. ft, c) number of tubes and d) average velocity of water, ft/s

Problem No.3: A single pass condenser with 5/8- inch OD tubes whose effective length is 18 ft and whose thickness is 0.046 inch receives 112,000 lb/hr of steam at 84 °F with an enthalpy of 960 BTU/b. The resulting condensate leaves at 84 °F with little change in kinetic energy. Circulating water enters the tube counter flow at 680°F and leaves at 78 °F. If the heat transfer coefficient is Uo= 630 BTU/HR ft? °F, find: a) the rate of flow of water, GPM, b) heating surface area, sq. ft, c) number of tubes and d) average velocity of water, ft/s s
