For their critical rotation speed N c, the surface area of the ring must be equal to the initial ballcontaining fraction at rest that reads (10) π R 2 −R 2 1 =απR 2 where R 1 stands for the ring's inner distance from the center of the jar and α denotes the volume filling fraction. Our ballcontaining fraction and his volumefilling fraction are the same.
