A single-effect evaporator is to be used to concentrate a 15 wt% NaOH solution to 40 wt% by condensing 20.7 psig-dry saturated steam in the steam coil. The coil surface is 930 ft in area, and an overall-heat-transfer coefficient of 250 Btu/h-ft-F is realized. With the pressure over the solution constantly at 1.93 psia, calculate the feed rate in the evaporator. The feed temperature is at 100F.
