A swimming pool whose volume is 10,000 gal contains water that is 0.03% chlorine. Starting at t=0, city water containing 0.002% chlorine is pumped into the pool at a rate of 5 gal/min. The pool water flows out at the same rate. What is the percentage of chlorine in the pool after 1 hour? When will the pool water be 0.004% chlorine?
