The Kinematic Viscosity (ν) calculator computes kinematic viscosity (ν) based on the ratio of viscosity (μ) and the density of a fluid (ρ).
INSTRUCTIONS: Choose units and enter the following:
- (μ) viscosity of a fluid
- (ρ) density of a fluid
Kinematic Viscosity (ν): The calculator returns the kinematic viscosity in m²/sec.
The Math / Science
Kinematic viscosity is also known as momentum diffusivity. Kinematic Viscosity (ν) is the ratio of dynamic viscosity (μ) and the density of a fluid (ρ). Since, μ is in units of (kg/m²)/ sec and ρ is kg/m³, the Kinematic Viscosity is expressed in units of m²/sec. The formula for kinematic velocity is:
υ = μ / ρ
where:
- υ is the kinematic viscosity
- μ is the dynamic viscosity
- ρ is the density
