**Stream Density** is a general basic physical term that is used in the following areas:

- in the case of transport phenomena ( heat transfer , mass transfer, and hydroaerodynamics ), the flux density of a scalar quantity is understood to mean the quantity of this quantity that passes through a unit area per unit time. Usually flux density$f$ determined by the formula$f\overrightarrow{v}$ / V, where V is the volume over which
*f*is distributed. - in electrodynamics , flux is usually defined as the integral of a vector quantity over a finite surface.
