Richardson and Zaki (1954) formulated a correction function for determining the sedimentation velocity of a suspension of particles on the basis of the velocity of a single particle not subject to forces other particles in the suspension. The Reynolds number for the flow is less than 0.25, so the Stokes equation can be used to calculate their velocity. The exponent in the Richardson and Zaki correction function is n = 4.65, independent of size. This paper describes research with micro particles in which the value of the exponent of the Richardson and Zaki correction function was found to be inversely dependent on the size of the micro particles.
