What Does Poiseuille S Law Explain

Poiseuille s law definition the law that the velocity of a liquid flowing through a capillary is directly proportional to the pressure of the liquid and the fourth power of the radius of the capillary and is inversely proportional to the viscosity of the liquid and the length of the capillary. The law is an algebraic equation poiseuille s law.

Poiseuille S Law And The Viscosity Of Fluids

Clinical applications of tuning forks.

What does poiseuille s law explain. Medical definition of poiseuille s law. In nonideal fluid dynamics the hagen poiseuille equation also known as the hagen poiseuille law poiseuille law or poiseuille equation is a physical law that gives the pressure drop in an incompressible and newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section. The direction of flow is from greater to lower pressure.

The viscosity n of the fluid the pressure gradient across the tubing p and the length l and diameter r of the tubing. Poiseuille s law the flow of fluids through an iv catheter can be described by poiseuille s law. The role of the bicarbonate buffer system in regulating blood ph.

Poiseuille 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. Positive law as used in opposition to natural law may be considered in a threefold point of view. It can be successfully applied to air flow in lung alveoli or the flow through a.

This is the currently selected item. Using optical traps to manipulate single dna strands. Flow rate q is directly proportional to the pressure difference p 2 p 1 and inversely proportional to the length l of the tube and viscosity η of the fluid.

The law is an algebraic equation. It states that the flow q of fluid is related to a number of factors. The universal voluntary law or those rules which are presumed to be law by the uniform practice of nations in general and by the manifest utility of the rules themselves.

Flow and poiseuille s law in operation. A statement in physics. At a constant driving pressure the flow rate of liquid through a capillary tube is directly proportional to the fourth power of the radius of the tube and inversely proportional to the length and viscosity of the tube.

Poiseuille 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. Poiseuille s law applies to laminar flow of an incompressible fluid of viscosity η through a tube of length l and radius r. The velocity of the steady flow of a fluid through a narrow tube as a blood vessel or a catheter varies directly as the pressure and the fourth power of the radius of the tube and inversely as the length of the tube and the coefficient of viscosity.
