Flow equation blood
WebThis equation describes laminar flow through a tube. It is sometimes called Poiseuille’s law for laminar flow, or simply Poiseuille’s law. Example 1: Using Flow Rate: Plaque Deposits Reduce Blood Flow ... Adjustments to blood flow are primarily made by varying the size of the vessels, since the resistance is so sensitive to the radius ... WebPoiseuille's Law relates the rate at which blood flows through a small blood vessel (Q) with the difference in blood pressure at the two ends (P), the radius (a) and the length (L) of the artery, and the viscosity (n) of the blood. The law is an algebraic equation, You can explore this law as it applies to arterioles through a number of ...
