Kinematic Viscosity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Kinematic viscosity, abbreviated as \(\nu \) (Greek symbol nu), is the ratio of dynamic viscosity to density or the resistive flow of a fluid under the influance of gravity.             

Kinematic Viscosity Formula

\(\large{ \nu = \frac{\mu}{\rho}  }\)

\(\large{ \nu =  Pr  \;  \alpha  }\)     (Prandtl number)

\(\large{ \nu =  Sc \; D_m  }\)     (Schmidt number)      


\(\large{ \nu }\)  (Greek symbol nu) = kinematic viscosity

\(\large{ \rho }\)  (Greek symbol rho) = density

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

\(\large{ D_m }\) = mass diffusivity

\(\large{ Pr }\) = Prandtl number

\(\large{ Sc }\) = Schmidt number

\(\large{ \alpha }\)  (Greek symbol alpha) = thermal diffusivity
