Volumetric flux
In fluid dynamics, the volumetric flux is the rate of volume flow across a unit area.
Volumetric flux = liters/. The density of a particular property in a fluid's volume, multiplied with the volumetric flux of the fluid, thus defines the advective flux of that property. The volumetric flux through a porous medium is often modelled using Darcy's law.
Volumetric flux is not to be confused with volumetric flow rate, which is the volume of fluid that passes through a given surface per unit of time.
