a single effect evaporator was used to concentrate 10 000 kg / hr of tomato juice from 5% total solids to 30% total solids. the juice enters the evaporator at 20 degrees Celsius. evaporator operated by steam (85% quality) at 143.27 KPA. Vacuum conditions in the evaporator allow the juice to boil at 75 degrees Celsius. the specific heat of the dilute material is 4.1 kj / (per kilogram of degree Celsius) and the concentrate product is 3.1 kj / (kg degree Celsius). calculate a. steam demand rate b. steam economy when the condensate temperature is released at 75 degrees Celsius
