Flow velocity : ウィキペディア英語版
Flow velocity
In continuum mechanics the macroscopic velocity, also flow velocity in fluid dynamics or drift velocity in electromagnetism, is a vector field which is used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar.
==Definition==

The flow velocity ''u'' of a fluid is a vector field
: \mathbf=\mathbf(\mathbf,t)
which gives the velocity of an ''element of fluid'' at a position \mathbf\, and time t\,.
The flow speed ''q'' is the length of the flow velocity vector
:q = || \mathbf ||
and is a scalar field.
