◦ Stokes Law Settling velocity is given by:

where vs is the particle's settling

velocity (m/s) (vertically downwards

if ρp > ρf, upwards if ρp < ρf ),

g is the gravitational acceleration

(m/s2), ρp is the mass density of the

particles (kg/m3), ρf is the mass

density of the fluid (kg/m3) and

μ is the dynamic viscosity (kg /m*s).
