Dynamic Viskosität

Overview

Dynamic viscosity ($\mu$) is a measure of a fluid's resistance to shear or tensile stress. It relates the shear stress in a fluid to the rate of strain (velocity gradient).

Key Formulas

Newton's Law of Viscosity

$\tau = \mu \frac{du}{dy}$

Shear stress is proportional to velocity gradient.

Kinematic Viscosity

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

Dynamic viscosity divided by density.
