Stokes Law - Physics of Particle Settling (Video)
Published on by Karl-Uwe Schmitz, President at Aqua Equip Technologies LLC (AET LLC) in Technology
In 1851 George Gabriel Stokes defined how drag forces affect spherical objects in a viscous fluid in the formula: Fd = 6pi * u * R * v.
An object in a viscous fluid like water always experiences a downward force – because of its weight and gravity – as well as an upward force. The upward force equals the weight of water which was displaced by the object.
This 3-minute video tutorial by AET provides a thorough explanation of Stoke's law.
