Design of triple effect evaporator (TEE) is shown below. The water content of incoming brine (NaCl +H2O) stream is reduced from 25 wt % to 3 wt %. If the evaporator unit is to produce 14,670 lb/hr of NaCl (includes 3 wt % H2O). Determine

a.The feed rate of brine in lb/hr.

b.The water removed from the brine in each evaporator.The data are shown in the accompanying figure.
