WebDec 13, 2010 · I only know one formula for Stokes' Law V = (2/9) * ( (Sphere) - (Fluid) ) * (g/m) * R 2 where m is the viscosity of the fluid This formula was derived using force equilibrium on the falling sphere Weight = Buoyancy Force + Drag Force and the units here are SI check this out : http://en.wikipedia.org/wiki/Stokes'_law WebStoke’s law was established by an English scientist Sir George G Stokes (1819-1903). When a spherical body moves down through an infinite column of highly viscous liquid, it drags the layer of the liquid in contact with it. As a result, the body experiences a retarding force. Then according to Stokes law, the viscous drag force, ,

WebIn an experiment to verify Stokes law, a small spherical ball of radius r and density ρ falls under gravity through a distance h in air before entering a tank of water. If the terminal velocity of the ball inside water is same as its velocity just before entering the water surface, then the value of h is proportional to : (ignore viscosity of air) WebIn 1854 Stokes suggested that the Fraunhofer lines might be caused by atoms in the outer layers of the Sun that absorb light of certain wavelengths. He failed to pursue the possibility, however, and later disclaimed any prior discovery when the German physicist Gustav R. Kirchhoff published his explanation of the Fraunhofer lines.

Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the … See more 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 … See more The force of viscosity on a small sphere moving through a viscous fluid is given by: $${\displaystyle F_{\rm {d}}=6\pi \mu Rv}$$ See more Although the liquid is static and the sphere is moving with a certain velocity, with respect to the frame of sphere, the sphere is at rest and liquid is flowing in the opposite direction to … See more • Batchelor, G.K.
