Continue reading our article for a simple explanation of Hagen-equation Poiseuille's in biophysics, as well as some practical applications like the flow velocity profile of a water pipe or blood flow in blood vessels.
Poiseuille's equation is also called as the Hagen-Poiseuille Law. In fluid dynamics computations, the Hagen-Poiseuille law is a simple formula. This equation represents the laminar flow in a cylindrical container, or, to put it another way, imagine a straight pipe with water flowing through it.
The Hagen-Poiseuille equation (Poiseuille's law) defines how much water flows through the pipe in one second, based on
The equation for Poiseuille Flow is given by the formula Q = (π * Δp * r4) / ( 8 * μ * l)
Hagen-Poiseuille equation for flow resistance is given by R = (8 * μ * l)/ (π * r4)

Now that we know what Poiseuille's equation is, we need to find out when we'll need to utilise it.
Only four simple steps are required to use our Poiseuille's equation calculator (or three if you want to calculate flow resistance)
Find the pressure difference (only required for the flow rate). If you don't know the pressure change, use the advanced mode button to enter your initial and final pressures, or use the formula below to subtract the final pressure from the start pressure
Change in pressure (Δp) = pressure 1 - pressure 2
Both the flow rate and the resistance will be included in Poiseuille's law calculator's output.
1. What is the formula for Poiseuille's Law?
Q=(P2−P1)πr48ηl is Poiseuille's law for flow in a tube. P2-P1=RQ is the pressure drop induced by flow and resistance.
2. What is the blood flow law of Poiseuille?
The volume flow rate is exactly proportional to the pressure gradient (difference in pressure per length of pipe section that we are studying) and the radius raised to the fourth power, according to Poiseuille's equation. This can lead to problems such as high blood pressure and complications.
3. Where is Poiseuille's law used?
The pressure drop of a constant viscosity fluid flowing laminarly through a rigid pipe can be calculated using Poiseuille's equation.
4. What is the significance of the Hagen Poiseuille law?
Using varying diameters of peripheral and central cannulas, the Hagen–Poiseuille equation can be used to calculate vascular resistance and, as a result, the flow rate of intravenous (IV) fluids.
