What is meant by Hagen Poiseuille equation?
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 is the Poiseuille law?
: a statement in physics: 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.
What did poiseuille do?
Jean-Louis-Marie Poiseuille, (born April 22, 1799, Paris, France—died Dec. 26, 1869, Paris), French physician and physiologist who formulated a mathematical expression for the flow rate for the laminar (nonturbulent) flow of fluids in circular tubes.
Where do I use Hagen Poiseuille equation?
Abstract. The Hagen-Poiseuille equation has been widely applied to the study of fluid feeding by insects that have sucking (haustellate) mouthparts.

What is the SI unit of input?
In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.
Is poiseuille unit of viscosity?
The poiseuille (symbol Pl) has been proposed as a derived SI unit of dynamic viscosity, named after the French physicist Jean Léonard Marie Poiseuille (1797–1869). The equivalent cgs unit, the poise, symbol P, is most widely used when reporting viscosity measurements.
