A triple effect evaporator is designed to reduce water from an incoming brine (NaCI + H2O) stream from 25 wt % to 3 wt %. If the evaporator unit is to produce 10,000 kg/hr of NaCl (along with 3 wt % H2O), determine: a) The feed rate of brine in kg/hr. b) The water removed from the brine in each evaporator. The data are shown in the accompanying figure.
