Stoke's Law : Settling velocity of a discrete particle depends upon specific gravity and diameter of the particle, gravitational acceleration (g) and kinematic viscosity of fluid (water in sedimentation treatment). Stoke's law relation is as follows Settling velocity, Vs =$\frac{g}{18}$($s_s$-1)$\frac{d^2}{v}$,

Where,

g = Gravitational acceleration,

$s_s$ = Specific gravity of …
