A 0.5 m diameter 20 m high stack releases gases at 500 K at a rate of 10 g/s into a steady 1.0 m/s wind. The exit velocity for the stack is 1.5 m/s and the stack diameter is 0.5 m. Assume an inversion height of 1.5 km. Estimate the maximum ground level concentration assuming rural stability class B. Repeat assuming rural stability classes C and D. How significant of an effect does the stability class have on the maximum ground level concentrations? Where does the maximum concentration occur for each of the three stability classes? Briefly comment on your results
