Venturi Meter Calculation PDF Calculator
Introduction & Importance
Venturi meters are widely used for flow rate measurement in various industries. The calculation of flow rates using venturi meters is crucial for process control and optimization. This calculator simplifies the process, providing instant results and insights.
How to Use This Calculator
- Enter the diameter of the venturi meter in millimeters.
- Enter the pressure drop across the venturi meter in Pascals.
- Click ‘Calculate’.
Formula & Methodology
The flow rate (Q) can be calculated using the following formula:
Q = C * A * sqrt(2 * ΔP / ρ)
Where:
- C is the discharge coefficient (assumed to be 0.95)
- A is the cross-sectional area of the venturi throat
- ΔP is the pressure drop
- ρ is the fluid density (assumed to be 1000 kg/m³ for water)
