Stokes' law makes the following assumptions for the behavior of a particle in a fluid: Laminar flow Spherical particles Homogeneous (uniform in composition) material Smooth surfaces Particles do not interfere with each other. For molecules Stokes' law is used to define their Stokes radius and diameter . See more In 1851, George Gabriel Stokes derived an expression, now known as Stokes' law, for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. Stokes' law is … See more Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend … See more Although the liquid is static and the sphere is moving with a certain velocity, with respect to the frame of sphere, the sphere is at rest and liquid … See more • Einstein relation (kinetic theory) • Scientific laws named after people • Drag equation See more The force of viscosity on a small sphere moving through a viscous fluid is given by: $${\displaystyle F_{\rm {d}}=6\pi \mu Rv}$$ where: • Fd is the frictional force – known as Stokes' drag – … See more Steady Stokes flow In Stokes flow, at very low Reynolds number, the convective acceleration terms in the Navier–Stokes equations are neglected.
