A feed of 3000kg hhr of a 1.2t%NaOH salt Solution at 311K enters continuously im a single effect evaporator and is being evaporated to 3.0wt%. The evaporation is at atmospheric pressure and the area of the evaporator is 72m2. Saturated steam at 383.2K is supplied for heating. Since the solution is dilute, it can be assumed to have the same boiling point as water. The heat capacity of the feed com be taken as 4.10kJ/kgK Calculate the amounts of vapour and ligrid product and the overall heat transfer coefficient
