## Idea ## In fluid dynamics, we are often considered with the acceleration due to [[viscosity]], so we consider the viscosity $\nu$ of a fluid divided by its density $\rho$, which is called the **kinematic viscosity**. This is denoted $\mu$: $$ \mu = \frac{\nu}{\rho} $$ ## References ## See: * [Kinematic viscosity](http://en.wikipedia.org/wiki/Viscosity#Kinematic_viscosity), Wikipedia. category: mathematical methods [[!redirects kinematic viscosity]]
