A trash incinerator has an effective stack height of $100m.$ On a sunny day with

a $2\frac{m}{s}$ wind the concentration of sulfur dioxide $200m$ directly downwind is

measured at $5\mathrm{.}0{10}^{-5}\frac{g}{m^3}.$ Estimate the mass release rate $($in $\frac{g}{s})$ of sulfur

dioxide from this stack. Also estimate the maximum sulfur dioxide concentration

expected on the ground and its location downwind from the stack.
