Heat transfer coefficient in evaporatora 10 wt% naoh solution is concentrated to 40 wt% in an evaporator operating at 40 kpa. the feed enters the evaporator at a mass flow rate of 4200 kg/hr and a temperature of 21.1°c. the evaporator area is 1.12 m2. saturated steam at 110°c is used for heating. a)calculate the boiling point rise (bpr) in the evaporator; b)calculate the steam flow rate in kg/hr; c)calculate the overall heat transfer coefficient in units of w/(m2*k).
