settling velocity

settling velocity

[′set·liŋ və‚läs·əd·ē]
(fluid mechanics)
The rate at which suspended solids subside and are deposited. Also known as fall velocity.
(mechanics)
The velocity reached by a particle as it falls through a fluid, dependent on its size and shape, and the difference between its specific gravity and that of the settling medium; used to sort particles by grain size.
