This formula uses 3 Variables
Variables Used
Momentum Diffusivity - (Measured in Square Meter Per Second) - Momentum Diffusivity most commonly refers to the diffusion, or spread of momentum between particles (atoms or molecules) of matter, often in the fluid state.
Dynamic Viscosity - (Measured in Pascal Second) - Dynamic Viscosity of a fluid is the measure of its resistance to flow when an external force is applied.
Density - (Measured in Kilogram per Cubic Meter) - Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.

## Momentum Diffusivity Formula

Momentum Diffusivity = Dynamic Viscosity/Density
𝜈 = μviscosity/ρ

## What is Momentum Diffusivity?

Momentum diffusivity most commonly refers to the diffusion, or spread of momentum between particles (atoms or molecules) of matter, often in the fluid state. This transport of momentum can occur in any direction of the fluid flow. Momentum diffusion can be attributed to either external pressure or shear stress or both.
It is also known as kinematic viscosity and defined as the ratio of the viscosity μ to the density of the fluid ρ. It is usually denoted by the Greek letter nu (ν).

## What is the Physical Significance of Kinematic Viscosity?

Physical significance of kinematic viscosity of fluids: We can say it as a measure of diffusivity of momentum in that fluid. That means "how fast momentum can be transferred in that fluid between various layers and particles".

## How to Calculate Momentum Diffusivity?

Momentum Diffusivity calculator uses Momentum Diffusivity = Dynamic Viscosity/Density to calculate the Momentum Diffusivity, Momentum diffusivity most commonly refers to the diffusion, or spread of momentum between particles (atoms or molecules) of matter, often in the fluid state. Momentum Diffusivity is denoted by 𝜈 symbol.
