02: A single-effect evaporator is concentrating a feed solution of organic colloids from (5 to 50wt%). The solution has a negligible boiling point elevation. The heat capacity of the feed is 4.06kJ/kg.K and the feed enters at 15.6°C. Saturated steam at 101.32kPa. A total of 4536kg/h of water is to be evaporated. The overall heat transfer coefficient is 1988 W/m².K. What is the required surface area and the steam consumption?
