Stokes formula for the sedimentation velocity of a ball falling through an otherwise quiescent, dilute, random, neutrally-buoyant suspension of spherical particles is theoretically derived, with Einstein's formula for the viscosity 'seen' by the ball in Stokes formula. The novelty of the analysis is described. In a series of experiments using falling-ball viscometry on suspensions of large, uniform spheres in Newtonian liquids, the authors verify their conclusions.
