The circulatory system provides many examples of Poiseuille’s law in action—with blood flow regulated by changes in vessel size and blood pressure. Blood vessels are not rigid but elastic. Adjustments to blood flow are primarily made by varying the size of the vessels, since the resistance is so sensitive to the radius. During vigorous exercise, blood vessels are selectively …

Poiseuille's Law What it Shows J. L. M. Poiseulle and G. H. L. Hagen determined that the laminar flow rate of an incompressible fluid along a pipe is proportional to the fourth power of the pipe's radius. To test this idea, we'll show that you need sixteen tubes to pass as much water as one tube twice their diameter. A YouTube video of our Poiseuille's Law apparatus in action …

Frequently Asked Questions

What is poiseuilles law?

Poiseuille’s law applies to laminar flow of an incompressible fluid of viscosity η through a tube of length l and radius r. The direction of flow is from greater to lower pressure. Flow rate Q is directly proportional to the pressure difference P2 − P1, and inversely proportional to the length l of the tube and viscosity η of the fluid.

How do you calculate poiseuilles law?

Poiseuille's lawshows the enormous influence of the vessel diameter on the rate of blood flow rate (Q = ([DELTA][Pr.sup.4]/[eta]L8)) [31], where Q is the flow rate ([cm.sup.3]/sec), P is the pressure (mmHg), r is the radius of the vessel (m), [eta] is the viscosity of blood (Pa*s), and L is the length of the vessel (cm).

What is poiseuilles law flow rate q?

Poiseuille's Law Flow Rate (Q): The calculator returns the flow rate in milliliters per minute (mL/min). However, the can be automatically converted to compatible units via the pull-down menu.

What is the difference between poiseuille flow and viscosity?

Viscosity: Poiseuille Flow 1 Laminar flow: smooth flow of the fluid in layers that do not mix. Turbulent flow: swirls that mix layers of fluid together. 2 Viscosity is a quantity expressing the magnitude of internal friction in a fluid, defined based on laminar flow. 3 Poiseuille’s law describes the pressure-induced, laminar flow through a tube.
