Question

What is fluid flow velocity?

Answer 1

In continuum mechanics the macroscopic velocity, also flow velocity in fluid dynamics or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar.

Answer 2

The linear rate of mass movement usually in -meters/second by itself it implies nothing about volume or pressure.

This is a point measurement which will usually vary throughout a system . Averages of the flow velocity are needed to calculate a volumatric flow rate .
