Blood flow The velocity v of blood that flows in a bloodvessel with radius R and length l at a distance r from the central axis is v(r)=(P)/(4 ηl)(R^2-r^2) where P is the pressure difference between the ends of the vessel and ηis the viscosity of the blood (see Example 3.3 .9 ). Find the average velocity (with respect to r ) over the interval 0⩽r ⩽R . Compare the average velocity with the maximum velocity. | Numerade
