In the process, three evaporators are used in series to reduce the water level of an incoming brine solution which contains 25% NaCl and 75% water. At the end of the three evaporators, the final product (97% NaCl, 3% water) is exiting at a rate of 14670 Ib/hr. Coming out of the top of each evaporator is pure water. Coming out of evaporator #1 (heading to evaprtor#3) is a solution of 33% NaCl and 67% water. Coming out of evaporator #2 (heading to evaporator #3) is a solution of 50% NaCl and 50% water.

A)Draw and label the diagram.

B)How many unknown streams are there? List them

C)Where can we write balances? Write out all of the independent material balances for each location.

D)What is the feed rate of brine in Ib/hr

E)How much water is removed at each evaporator?
