The results for the K theory line source model agree favorably
with Sutton's mean field trial data. As shown in Figure 1, the peak
concentration at 100 m downwind is 35 mg m-3 for both. At longer
downwind distances the calculated results are lower than those given by
"mean field trial data. The difference gradually increases until at 1000
m the calculated value is 9C% of that computed from Sutton's criteria
and 70% at 10000 m downwind. The calculated cloud height at 100 m
downwind of a line source is 11 m as compared to 10 m from the mean
field trial data. The calculated height is obtained from Figure 5, with
retention efficiency E = 0, where the concentration has fallen to
one-tenth of the value on the ground.
