By definition, flow (q) as a function of time, passing through a section of a vessel is written:
$$ q(t) = s(t).\bar v(t) $$
s(t) is the section of the vessel at time t;

v(t) is the mean velocity of the blood through the whole of the vessel’s section (mean spatial velocity), that is the speed which could replace all the different speeds occurring on a section, with the flow remaining the same (Fig. 1).
