It is necessary to evaluate the performance of an evaporator that will be used to concentrate a 5% organic solution. Assume there will be no boiling point rise. The following information has already been obtained: U=300Btu/hrft^2F; A= 2000ft^2; heating steam S is available t 4.5 psia; feed enters at 140F. Must aby further measurements be made? The rate of heat transfer from the steam coils to the liquid is Q=UA(Ts-Tv)
