1) Stokes Law :-
Stokes law states that the terminal velocity of settling of spherical particle in suspension, varies with square of the diameter of the sphere, density and viscosity of the field and the density of the sphere,
$V_s = \frac{g(P_s - P_w)}{18 \mu}$
$D = [\frac{\frac{18 \mu}{g}}{(G-1)P_w}*\frac{}{}]^\frac{1}{2}$
Where $P_s = G.P_w$ is the density of solid sphere of diameter,
$\mu,P_w$ = vicosity of fluid and density respectively,
$V_s$ = Terminal Velocity = $\frac{H}{t}$
H = Distance from Surface.
