How To Calculate Reynolds Number In Venturi Meter

Introduction & Importance

Calculating the Reynolds number in a Venturi meter is crucial for understanding and predicting fluid flow behavior. It helps in designing and optimizing piping systems, predicting flow regimes, and more.

How to Use This Calculator

1. Enter the diameter of the Venturi meter.
2. Enter the fluid velocity.
3. Enter the fluid density.
4. Enter the fluid viscosity.
5. Click ‘Calculate’.

Formula & Methodology

The Reynolds number (Re) is calculated using the formula:

Re = (V * D) / (μ / ρ)

Where:

• V = Velocity (m/s)
• D = Diameter (m)
• μ = Viscosity (Pa·s)
• ρ = Density (kg/m³)
