ABSTRACT
Stokes' Law Stokes (1856), an English physicist, proposed an equation for determining the terminal velocity of a falling sphere in a liquid. If a single sphere is allowed to fall through a liquid of indefinite extent, the terminal velocity, v can be expressed as,

in which, distance L
v = terminal velocity of fall of a sphere through a liquid =--- time
= unit weight of solid sphere Yw = unit weight of liquid J.l = absolute viscosity of liquid D = diameter of sphere.
