Viscosity is the resistance of a fluid to flow, and … WebStatement of the law. The force of viscosity on a small sphere moving through a viscous fluid is given by: = where (in SI units): . F d is the frictional force – known as Stokes' drag – acting on the interface between the fluid and the particle (newtons, kg m s −2);; μ (some authors use the symbol η) is the dynamic viscosity (Pascal-seconds, kg m −1 s −1);
WebJun 6, 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 … WebApr 6, 2024 · Stoke's law explains the main reason why raindrops falling from the sky do not harm us on the ground. Stokes law is an extremely important concept that is a part of physics Stokes Law Formula Stokes came up with this formula in 1851 to calculate this drag force or frictional force of spherical objects immersed in viscous fluids.
WebApr 7, 2024 · Stokes’ Law Definition A mathematical equation that expresses the settling velocities of the small spherical particles in a fluid medium is known as Stokes’ Law. This law is derived by considering the forces acting on a particular particle as it sinks through the liquid column under the influence of gravity. WebThe Stoke law is a simple physical model that describes the frictional force exerted on spherical objects by a fluid when the objects are in motion. The Stoke law is valid for small particles, whose radius is much smaller than the characteristic length scale of the flow.
