Definition

EN

scalar (ISO 80000-2: Mathematics) quantity characterizing the total flow through the two-dimensional domain A with the normal vector

e n of a flowing fluid with velocity v

(ISO 80000-3: Space and time) as an integral:

q V = & # 8748 ; A v ⋅ 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

FR
