Wastewater is being dumped into a lake. The input flow of $0\mathrm{.}10\frac{m^3}{s}$ of

nonconservative pollutant is with a concentration of $30\mathrm{.}0m\frac{g}{L}$ and reaction rate of

o$\mathrm{.}20/$day$.$ The effluent from the lake must have pollutant concentration of less than

$10\mathrm{.}0m\frac{g}{L}.$ The lake's volume is at a steady state.

What is the volume of the lake assuming complete mixing?
