Chloropicrin, also known as PS and nitro-chloroform, is a chemical compound currently used as a broad-spectrum antimicrobial, fungicide, herbicide, insecticide, and nematicide. In World War I, the Germans used it as tear gas since it is also an airway irritant. This substance is a liquid at room temperatures. Suppose there was a small spill of this material on a paved surface at a chemical plant. The spill has a width of 0.8 ft. and a length of 2.5 ft. The prevailing wind is 10 miles per hour in a direction parallel to the length of the spilled material. Estimate the rate of evaporation in grams per hour of this material. Chloropicrin has a diffusivity in air of 0.088 cm2 s−1. At 25°C, its vapor pressure is such that its equilibrium concentration in air would be equal to 0.211 g L−1. The kinematic viscosity of air under these conditions is 0.157 cm2 s−1. Carefully state your assumptions.
