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 derived by solving the Stokes flow limit for small Reynolds numbers of the … 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 … See more Steady Stokes flow In Stokes flow, at very low Reynolds number, the convective acceleration terms in the Navier–Stokes equations are neglected. Then the flow equations become, for an incompressible steady flow: See more • Einstein relation (kinetic theory) • Scientific laws named after people • Drag equation • Viscometry See more Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube.

WebJun 23, 2024 · Stokes Theorem Proof. Let A vector be the vector field acting on the surface enclosed by closed curve C. Then the line integral of vector A vector along a closed curve is given by. where dl vector is the length of a small element of the path as shown in fig. Now let us divide the area enclosed by the closed curve C into two equal parts by ... WebThe Gauss divergence theorem states that the vector’s outward flux through a closed surface is equal to the volume integral of the divergence over the area within the surface. The sum of all sources subtracted by the sum of every sink will result in the net flow of an area. Gauss divergence theorem is the result that describes the flow of a ...
WebThe flow rate depends on the fluid’s viscosity, the cross-sectional dimensions of the pipe, and the pressure gradient. Poiseuille's law can be determined from a simple procedure involving dimensional analysis. Poiseuille’s law describes flow rate in a pipe and applies to areas like fluid flow in a capillary tube. WebFor Stokes' theorem to work, the orientation of the surface and its boundary must "match up" in the right way. Otherwise, the equation will be off by a factor of -1 −1.
