WebStoke’s law was established by an English scientist Sir George G Stokes (1819-1903). When a spherical body moves down through an infinite column of highly viscous liquid, it drags the layer of the liquid in contact with it. As a result, the body experiences a retarding force. Then according to Stokes law, the viscous drag force, , WebOct 7, 2024 · Stoke’s Law Derivation. The viscous force acting on a sphere is directly proportional to the following parameters. the radius of the sphere. coefficient of viscosity. the velocity of the object. Mathematically, this is represented as. Now let us evaluate the values of a, b and c. Substituting the proportionality sign with an equality sign, we ...
