QUESTION $2$: $[25$ MARKS$]$

Determine the allowable emission rate of dust fall from an air contamination source. Use the following data:

Ground level particle fall rate, $q=1\mathrm{.}86{10}^{-6}\frac{g}{m^2}\frac{?}{s}$

Terminal settling velocity for $25m$ quartz, $v=0\mathrm{.}03\frac{m}{s}$

Ground$-$level particle concentration, $f=\frac{q}{v}$

Mean wind velocity, $u=3\mathrm{.}8\frac{m}{s}$

Isotropic diffusion coefficient, $C^2=0\mathrm{.}01$

Stability parameter, $n=0\mathrm{.}25$

Effective stack heights, $H_e=10m,20m,40m,60m,$ and $80m$

Horizontal distance from the stack to the nearest property line, $x=100m,200m,250m,300m,400m500m,$ and $1000m$

Present all the values of the allowable emission rate for each horizontal distance and stack height in tabular format.
