Viscosity Apparatus Stoke’S Method

George Gabriel Stokes, an Irish born mathematician, worked most of his professional life describing fluid properties. Perhaps his most significant accomplishment was the work describing the motion of a sphere in a viscous fluid. This work lead to the development of stokes law, a mathematical description of the force required to move a sphere through a quiescent, viscous fluid at specific velocity. This law will from the basis of this laboratory investigation.

A viscosity apparatus (Stokes method) typically consists of one meter long, 35mm diameter graduated glass tube mounted vertically in a metal stand, The lower sides of tube is closed, where as on the upper end, rubber cork with hole is provided.
