A rainstorm deposits 0.1 in./h of rain over a large area. The drops have an average diameter of 2 mm for which the target efficiency for the particles in air is estimated to be 0.1. Given that the initial concentration is 100 μg/m^3, how long (in hours) will it take for the particle concentration to reduce to 10 μg/m^3?
