WebIn order to find the weight of the drop, Millikan allowed the drop to fall through air. It quickly reaches its terminal velocity. At this point, the weight is being balanced by the viscous drag of the air. The drag can be calculated from Stokes' Law … WebStokes’ law is an equation used to calculate the terminal velocity of a hard sphere falling through a continuous medium makes use of a dynamic viscosity, but as we’ve seen emulsions are often non-Newtonian and show shear thinning behaviour with increasing shear rates. So what viscosity value should be used? fky infoStokes' 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.
