Law of Impact

Japanese: インパクト則 - いんぱくとそく
Law of Impact

…The relationship between particle size and flow velocity, which indicates the settling and cessation (accumulation) of flowing particles, is generally shown in a graph by F. Hjulström and Å. Sundborg (Figure). The settling of particles in still water follows Stokes' law or impact law (also called Newton's law). Stokes' law is well suited to small particles with a diameter of 0.1 to 0.001 mm, and the settling velocity v is expressed by the following equation. …

*Some of the terminology explanations that mention the "impact law" are listed below.
