Definition:Kinematic Viscosity

Definition

The kinematic viscosity of a fluid is its dynamic viscosity divided by its density:

$\nu = \dfrac \eta \rho$

where:

$\eta$ denotes the dynamic viscosity

$\rho$ denotes the density.

Symbol

$\nu$

The usual symbol used to denote the kinematic viscosity of a fluid is $\nu$.

Its $\LaTeX$ code is \nu .

Dimension

The dimension of measurement of kinematic viscosity is $\mathsf {L^2 T^{-1} }$.

Units

The SI unit of measurement of kinematic viscosity is the square metre per second.

The CGS unit of measurement of kinematic viscosity is the square centimetre per second.

The FPS unit of measurement of kinematic viscosity is the square foot per second.
