SEDIMENTATION Thermopedia

A particle or droplet will settle in a fluid if its density is greater than that of the fluid in which it is suspended. The (laminar) settling velocity of particles whose concentration is very low, that is when the flow of fluid around a particle does not affect the flow around neighboring particles, can be calculated from Stokes Law:
