Question Help 1.5.45 A shallow reservoir has a one-square-kilometer water surface and an average water depth of 4 meters. Initially it is filled with fresh water, but at timet=0 water contaminated with a liquid pollutant begins flowing into the reservoir at the rate of 500 thousand cubic meters per month. The well-mixed water in the reservoir flows out at the same rate. Your first task is to find the amount x(t) of pollutant (in 40- millions of liters) in the...
