Suppose you have a 200-gallon tank full of fresh water. A drain is opened that removes 3 gal/sec from the tank and, at the same moment, a valve is opened that lets in a 1% solution (a 1% concentration) of chlorine at a slower rate of 2 gal/sec. A.) When is the tank half full and what is the concentration of the chlorine then? B.) If the drain is closed when the tank is half full and the tank is allowed to fill, what will be the final concentration of chlorine in the tank?
