Stokes' law

The expression for the drag force given by equation (6) is called Stokes' law.

The hydrodynamic resistance force is evaluated following the Stokes' law.

Thus Stokes' law is adequate for most practical situations.

The drag force acting on the drop can then be worked out using Stokes' law:

Stokes' law finds many applications in the natural sciences, and is given by:

Stokes' law makes the following assumptions for the behavior of a particle in a fluid:

Stokes' law for friction force in a viscous fluid.

Because the method depends on Stokes' Law the dynamic viscosity of the water is important.

However, Stokes' law is only valid when the velocity of the gas at the particle's surface is zero.

This became known as Stokes' law.

Under the condition of low Re, the relationship between force and speed of motion is given by Stokes' law.

Note that for molecules Stokes' law is used to define their Stokes radius.

The attenuation coefficient is , following Stokes' law (sound attenuation).

The Reynolds number is very small and Stokes' Law can be used to measure the viscosity of the fluid.

Generally, for small particles (laminar approximation), it can be calculated with Stokes' Law.

By using the Stokes' law , we can estimate the sedimentation rate of the particle in Liquid.

Stokes' law can be used to calculate the size of a settling basin needed in order to remove a desired particle size.

Stokes' law applies to sound propagation in an isotropic and homogeneous Newtonian medium.

For dilute suspensions, Stokes' law predicts the settling velocity of small spheres in fluid, either air or water.

Bulk viscosity explains the loss of energy in those waves, as described by Stokes' law of sound attenuation.

Assuming Stokes' law, the drag force on any particle in this inlet stream is therefore given by the following equation:

When the particle Reynolds number indicates laminar flow, Stokes' law can be used to calculate its fall velocity.

Stokes' law can refer to:

Particles can remain in suspension in the ocean or freshwater, however they eventually settle (rate determined by Stokes' law) and accumulate as sediment.

The importance of Stokes' law is illustrated by the fact that it played a critical role in the research leading to at least 3 Nobel Prizes.
