Stokes-Einstein Equation

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Stokes-Einstein equation, abbreviated as SE, is used for evaluating diffusion of spherical particles through a liquid with low Reynolds numbers.

 

Stokes-Einstein Equation

\(\large{ F =  \frac{ k_b \; T }{ 6 \; \pi \; \mu \; r }   }\)   

Where:

\(\large{ D }\) = diffusion coefficient

\(\large{ k_b }\) = Boltzmann constant

\(\large{ \mu }\) (Greek symbol mu) = dynamic viscosity

\(\large{ \pi }\) = Pi

\(\large{ r }\) = radius of spherical parcticle

\(\large{ T }\) = temperature
