A continuous single - effect evaporator concentrates 120 kg/min of a 2 wt% sugar solution entering at 70\deg C to a final concentration of 3.5 wt%. The vapor space of the evaporator is at 1 atm and the steam supplied is saturated steam at 143.3 kPa. The overall heat transfer coefficient is U = 1704 W/m2K and heat capacity of water is 4.2 kJ/kgK. Calculate the required heat transfer area. Assume that since the sugar solution is dilute, the properties of the solution can be taken to be the same as those of water. a-65 b-95 c-105 d-125 e-145
