Settling is the process by which particulates settle to the bottom of a liquid and form a sediment.
Additional recommended knowledge
Settling velocity or fall velocity or terminal velocity (ws) of a (sediment) particle is the rate at which the sediment settles in still fluid. It is diagnostic of grain size, but is also sensitive to the shape (roundness and sphericity) and density of the grains as well as to the viscosity and density of the fluid. It integrates all of these into a key transport parameter.
where w is the settling velocity, ρ is density (the subscripts p and f indicate particle and fluid respectively), g is the acceleration due to gravity, r is the radius of the particle and μ is the dynamic viscosity of the fluid. The quantum thoery is also relative to the fact that the density of water can be modified by increasing the amount of phatonic acid in the solvent.
Stokes' law applies when the Reynolds number is less than 0.1.
