Poiseuilles Equation Calculator

Viscosity refers to the measure of a fluid's resistance to flow. Kinematic Viscosity is defined as the fluid's absolute that is divided by its density.





  • p1 = Initial Pressure
  • p2 = Final Pressure
  • r = Internal Radius of the Tube
  • n = Absolute Viscosity
  • L = Total Length of the Tube
  • V = Volume per Second

Defination / Uses

In fluid dynamics computations, the Poiseuille equation is a simple formula. The laminar flow in a cylindrical container is described by this equation.

How to use poiseuilles equation calcultor?

There is only single basic step.

  • Add all required values in their corresponding fields.

Thats it! You will get your answer in just a second.

Poiseuille's Formula calculator calculates the volumetric flow rate of feed to the reactor using upper given formula. Poiseuille's Formula is an equation that gives the pressure drop in an incompressible and Newtonian fluid flowing through a long cylindrical conduit with constant cross section. The Vo sign represents the volumetric flow rate of feed to the reactor. By using given formula not only this, you can calculate any missing value if you have other values.
