Coming home after the end of the winter semester, you find that your family’s swimming pool has not be maintained well. In particular, it has no chlorine residual at all, and it is full of tree leaves. You buy a concentrated chlorine solution (1% as Cl2) and begin to meter it into the pool at a rate of 100 mL/hour. The pool has a volume of 200 m3. You also add new water, and remove in-pool water, at a rate of 3.785 L/minute. The chlorine reacts with the organic matter in the with a rate of 0.5/hour. How long will it take to get the Cl2 residual up to 1 mg/L if you add Cl2 continously

Coming home after the end of the winter semester, you find that your family’s
swimming pool has not be maintained well. In particular, it has no chlorine
residual at all, and it is full of tree leaves. You buy a concentrated chlorine
