which applies up to [Re.sub.t] = 260 000 for free settling (Haider and Levenspiel, 1989), but only for regime (2) in the case of free rising, for which [Re.sub.t] = [U.sub.t][[rho].sub.f]d/[mu] is the terminal-velocity Reynolds number.
(1996), for free rise of a light solid sphere with Ar/[d.sup.2] > 1.18 x [10.sup.4] [mm.sup.-2], the drag coefficient does not follow the standard curve of a free settling sphere and has a constant value of 0.95: Ar/[d.sup.2] is 1.29 x [10.sup.4] [mm.sup.-2] and 1.53 x [10.sup.4] [mm.sup.-2] for the spheres of diameters 15.0 and 19.1 mm, respectively.

To this must be added allowances for the transition and free settling zones, and feed disturbance to obtain a total depth of tank.
