sometimes referred to as the centerline velocity
zero at the vessel wall, when r=ri.
is that of a parabola, hence the velocity profile
across the vessel wall is
as a parabolic velocity profile. This is
the parabolic velocity profile. The velocity is maximal at
centerline and decreases progressively towards the vessel wall in a parabolic fashion.
The amount of flow,
volume flow, is obtained as,
which results in the well-known Poiseuille equation
The average velocity across the velocity profile is simply the amount
the cross-sectional area
