At higher volume fractions ϕ > 0.2, the rate of sedimentation v becomes a complex function of ϕ. V decreases exponentially with increase in ϕ, and it approaches 0 when ϕ approaches the maximum packing fraction ϕ p. The latter is equal to 0.74 for hexagonal close packing of equal-sized particles, and it is equal to 0.64 for random packing.Web
