In an experiment to verify stokes law
WebAug 18, 2024 · It was done in the 1840’s by Sir George Gabriel Stokes. He found what has become known as Stokes’ Law: the drag force F on a sphere of radius a moving through a fluid of viscosity η at speed v is given by: (1.7.1) F = 6 π a η v This drag force is directly proportional to the radius. WebFeb 2, 2024 · Stokes’ law is used in the falling-sphere viscometer, in which a sphere of known density descends a vertical tube. The terminal velocity can be measured by recording the time and the distance traveled. This device is used to measure the viscosity of a fluid.
