For gravity settlers and cyclone separators, this force is proportional to the cube of the diameter of particles of constant density. In ESPs, though the resistance force offered by the viscous medium is Stokes’ drag, the force driving the particle to the wall is electrostatic which is proportional to the square of the particle diameter.
