Alake with the constant volume 10 *10^6 is fed by a
pollutionfree stream with the flow rate 50m^3/s. a factory dumps
5m^3/s of anonconservative waste with concentration 100mg/l into
the lake. thepollution has a reaction rate coefficient of 0.25/day.
assuming thepollution is well mixed in the lake, find the steady
stateconcenration of pollution in the lake.
