Web6 jun. 2024 · Stoke’s Law is an equation that expresses the settling velocities of small spherical particles in a fluid medium. The law is established by taking into account the forces acting on a certain particle as it falls through a liquid column under the influence of gravity. WebThis laboratory investigation involves determining the viscosity and mass density of an unknown fluid using Stokes' Law. Viscosity is a fluid property that provides an indication of the resistance to shear within a fluid. … randrepeatWebStokes Law, named after George Gabriel Stokes, describes the relationship between the frictional force of a sphere moving in a liquid and other quantities (such as particle radius and velocity of the particle). If a sphere or a body moves through a fluid, a friction force must be overcome. Table of contents Stokes Law (laminar flow around a sphere) overwatch dc群

"Web9 apr. 2024 · 2. The first equation is not necessarily wrong. When a sphere passes through a fluid at "low" speed the drag on the sphere is given by 6 π R v η and this is known as Stokes's law. Derivation of this equation is difficult and requires a number of assumption to be made including that the fluid flow must be laminar. " - Law of stokes
