Cleaning Up Lake Erie Lake Erie has a volume of roughly 100 cubic miles. and its equa1 inflow and outflow rates are 40 cubic miles per year. At year t = 0. a certain pollutant has a volume concentration of 0.05%:. but after that the concentration of pollutant flowing into the lake drops to 0.01 %. Answer the following questions. assuming that the pollutant leaving the lake is well mixed with lake water. (a) What is the IVP satisfied by the volume V (in cubic miles) of pollutant in the lake? (b) What is the volume V of pollutant in the lake at time t ? (c) How long will it take to reduce the pollutant concentration to 0.02% in volume?
