Abstract

According to Stokes law which is well fulfilled within the range of 0.1–30 μm, the velocity of gravitational deposition (sedimentation) and scavenging with precipitation for particles is proportional to their surface area, i. e. to D 2 (D - particle size). With D less than 0.1 μm, their behavior is similar to that of “weightless” gas molecules and the velocities of surface dry deposition and the efficiency of particle captures by precipitation increasing.
