Tomato juice having a concentration of 12 wt% solids is being concentrated to 25% solids in a film-type evaporator. The maximum allowable temperature for the tomato juice is 135 °F, which will be the temperature of the product. The feed enters at 100 °F. Saturated steam at 25 psia is used for heating. The overall heat-transfer coefficient U is 600 btu/h·ft2·°F and the area A is 50 ft2. The heat capacity of the feed cP is estimated as 0.95 btu/lbm·°F. Neglect any boiling-point rise if present. Calculate the feed rate of tomato juice to the evaporator.
