FE = qE vE = qE/(6πµr) vg = 2(ρw−ρair)gr²/(9µ)
MODEL & BOUNDARIES
Know what the result means.
Isolated spherical droplet, Continuum no-slip Stokes drag, still air near 20°C, no charge evolution or wall forces. Cunningham slip is omitted. Electrical drift is along qE; gravitational settling is downward. The calculator reports magnitudes separately and warns when Reynolds number leaves the low-Re regime.
