Dispersion in air can be a lot like dispersion in water, except the rates are different. A violent explosion results in the release of a slug of 5000 kg of a solvent (TCE) to a height of 300 m over a width of 300 m in air. (a) What is the concentration of TCE at a distance 0.5 km away four hours after the explosion? Assume mixing occurs only by eddies (no net motion of the air) with a mixing coefficient of 10 4 cm 2 s -1 . (b) What is the size of the plume, and how fast (i.e., its velocity) is the "front" moving, after 1 day, because of this turbulent eddy dispersion?
