The Richardson-Zaki equation is by far the most popular empirical equation used to describe the velocity-voidage relationship for sedimenting solid-liquid homogeneous suspensions, using only two empirical parameters. In this work some of Richardson and Zaki suggestions for the two parameters are challenged on the basis of new and old experimental evidence.
