Mixing in Two Tanks

Tank A contains 50 liters of brine in which 25 grams of salt are dissolved. Tank B contains 50 liters of brine in which 0 grams of salt are dissolved. Fresh water is pumped into tank A at a rate of 4 liters/minute; the well-mixed solution is pumped from tank A into tank B at 4 liters/minute. The well-mixed solution from tank B is pumped out at 4 liters/minute. This Demonstration uses colors and animation to visualize the solution to this problem.
