WebMar 21, 2024 · Is it possible to derive Stokes' law (Viscous force on a spherical body moving in a fluid fv = 6πηRv) without using the " ∇ " operator (at least not in that form) or other theorems/laws other than Newton's law of viscosity and Newton's laws of motion? If yes, can anyone demonstrate how to do it. Note: I have seen the Dimensional Analysis method.

WebIt was done in the 1840’s by Sir George Gabriel Stokes. He found what has become known as Stokes’ Law: the drag force on a sphere of radius moving through a fluid of viscosity at speed is given by: Note that this drag force is directly proportional to the radius . 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, , crystallization definition psychology
