Euler Number Calculator

Calculate the Euler number using: $$ Eu = \frac{\Delta P}{\tfrac{1}{2}\rho\,v^2} $$

* Enter the pressure difference $ \Delta P $ (Pa), fluid density $ \rho $ (kg/m³), and flow velocity $ v $ (m/s).

Step 1: Enter Parameters

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

e.g., 1000 Pa

Fluid Density, $ \rho $ (kg/m³):

e.g., 1000 kg/m³ for water

Flow Velocity, $ v $ (m/s):

e.g., 1 m/s
