What is Poiseuille’s law simplified? 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.
What is Poiseuille’s law used for? Definition. The flow of fluids through an IV catheter can be described by Poiseuille’s Law. It states that the flow (Q) of fluid is related to a number of factors: the viscosity (n) of the fluid, the pressure gradient across the tubing (P), and the length (L) and diameter(r) of the tubing.
What is Poiseuille law and Ohm’s law? The Hagen–Poiseuille equation describes the relationship between pressure, fluidic resistance and flow rate, analogous to voltage, resistance, and current, respectively, in Ohm’s law for electrical circuits ( V = R I ). Both electrical resistance and fluidic resistance are proportional to the length of the device.
What does Poiseuille’s equation tell us? Poiseuille’s equation states that the volume flow rate is directly proportional to the pressure gradient (difference in pressure per length of pipe section that we are considering) and the radius raised to the fourth power.
