Question

Tomato juice in a single acting climbing film evaporator has a soluble content of 12% 28% It is concentrated to soluble solids content. Heat transfer to tomato juice in the evaporation process 3 It is transferred as it rises in the pipe with a height of 4 m and a diameter of 4 cm. Tomato juice maximum The temperature value at which it can be processed is 57ºC, and the feed is also added to the evaporator at this temperature value. It enters. Energy source saturated steam 170 kPa to the evaporator under absolute pressure It enters. If the overall heat transfer coefficient is 6000 J.m-2 .sn-1 .ºC-1, entering the evaporator per hour Calculate the tomato juice feed current.
