Overview

Kinematic viscosity ( $\nu$ ) is the ratio of dynamic viscosity to density. It describes the fluid's resistance to flow under gravity and is the relevant viscosity for problems involving Froude or Reynolds numbers.

Key Formulas

Definition

$\nu = \frac{\mu}{\rho}$

Kinematic viscosity = dynamic viscosity / density.
