◦ 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).
