The principles that govern fluid motion in normal blood vessels can still be best approached by using the classic Poiseuille model. This law states that the ratio of the pressure gradient (PI - P2) to flow (Q) is a function of the tube dimensions and the viscosity (μ) of the moving fluid:
$$\frac{{P1 - P2}} {Q} = \frac{{8\mu L}} {{\pi (r^4 )}} $$
where r is the radius of the tube and L is the length of the tube. The ratio of pressure gradient (PI - P2) to flow (Q) is also defined as the vascular resistance (R).
