TLDR
Combining boundary layer theory and experimental data for the pressure distribution and boundary layer thickness over the surface of a sphere, the following expression was obtained for the drag coefficient: C D = 1+ 9.06 R e 1 2 2 Using this formula as a basis, an expression was developed for relating the settling velocity of spherical particles to their diameter at any value of the Reynolds Number as mentioned in this paper.About:

A simple formula for predicting settling velocity of sediment particles
TL;DR: Based on the general relationship described by Cheng between the drag coefficient and the Reynolds number of a particle, a new relationship between Reynolds number and a dimensionless particle parameter is proposed in this paper.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.
