Enter the magnitude of the charge, the strength of the electric field, viscosity of the medium and the Stoke’s radius into the calculator to determine the ion velocity.

Ion Velocity Formula

The following equation is used to calculate the Ion Velocity.

Vi = (Z*e*E) / (6*pi*n*r)

  • Where Vi is the ion velocity (m/s)
  • Z is the magnitude of the charge
  • e is the charge of one electron (C)
  • E is the strength of the electric field (N/C)
  • n is the viscosity of the medium (N*s/m^2)
  • r is Stoke’s radius of charged molecules (in,m)

What is an Ion Velocity?

Definition:

An ion velocity is a measure of the average speed of an ion within an electric field.
