Help with Poiseuille's Law
This calculator uses Poiseuille's Law to calculate the rate of flow of a fluid through a cylindrical pipe with laminar flow. The equation used is:
R = (pi*r4*(p1-p2)) / (8*n*L)Where:
- R = Rate of flow
- p1 = 1st pressure
- p2 = 2nd pressure
- n = viscosity of fluid
- L = length
- r = inside radius
The viscosity of the fluid is measured in dyne sec/cm2, poise.
