Definition

scalar (ISO 80000-2: Mathematics) quantity characterizing the total flow through the two-dimensional domain $A$ with normal vector $e_{n}$ of a flowing fluid with mass flow $j_{m}$ (mass flow) as an integral:

$q_{m} = & # 8748;_{A} j_{m} \cdot e_{n} d A$

where $d A$ is the area (ISO 80000-3: Space and time) of an element of the two-dimensional domain $A$

grandeur scalaire caractérisant l'écoulement total, à travers le domaine bidimensionnel $A$ de vecteur normal $e_{n}$ , d'un fluide en mouvement avec le flux massique $j_{m}$ (mass flow) sous forme d'une intégrale :

$q_{m} = & # 8748;_{A} j_{m} \cdot e_{n} d A$

où $d A$ est l'aire (ISO 80000-3: Space and time) d'un élément du domaine bidimensionnel $A$
