The flow velocity (V) is dependent upon the
geometry of the conduit through which the fluid flows and is
related to the volumetric flow as shown in the following formula
where Q represents the volumetric flow as cubic feet per second and
A represents the cross-sectional area of the conduit in square feet
to yield flow velocity in feet per second.
