Strokes law is derived by George Gabriel Strokes in 1851. It is the basis of the falling-sphere 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.Strokes law states that the force that resists the sphere's fall in a viscous fluid is directly proportional to the viscosity of the sphere, the radius of the sphere, and the viscosity of the fluid.
The value of k in 20°C in an aqueous medium is 34,700.
