Poiseuille's Law: Radial Dependence

We further explore flow by finally varying the radius. Setting the other parameters to the typical values of P=50 mmHg, n=0.05 P, and L=0.5 cm, Poiseuille's Law becomes

Q = 104.694 a4

where the radius is measured in millimeters (mm). The blood flow is proportional to the fourth power of radius. This is known as a power law.
