Volumetric Flow Rate Calculator

Calculate the volumetric flow rate using Poiseuille’s Equation: $$ Q = \frac{\pi\, \Delta P\, r^4}{8\, \mu\, L} $$

* Ensure that ΔP is in Pascals (Pa), r and L are in meters (m), and μ is in Pa·s.

Step 1: Enter Parameters

Pressure Difference, $\Delta P$ (Pa):

e.g., 1000 Pa

Pipe Radius, $r$ (m):

e.g., 0.05 m

Dynamic Viscosity, $\mu$ (Pa·s):

e.g., 0.001 Pa·s

Pipe Length, $L$ (m):

e.g., 1 m
