Using the data given below with the Gaussian plume equation to calculate the $S{O}_2$ concentration $($in $\frac{g}{m^3})$ at locations $1km$ downwind of the stack. $(4$ marks$)$

Emission rate $(Q)=120\frac{g}{s}$

Wind speed $(u)=4\frac{m}{s}$

Stability class is A

Effective stack height $(H)=30m$

Calculation the maximum concentration $($in $m\frac{g}{m^3})$and that downwind distance $($in $m)$ of the above condition? $(6$ marks$)$
