Vortex Flow Meter Pressure Drop Calculator
Vortex flow meters are widely used in various industries for measuring fluid flow rates. Understanding the pressure drop across these meters is crucial for system design, maintenance, and efficiency. Our calculator simplifies this process.
- Enter the flow rate, pipe diameter, fluid density, and roughness values.
- Click the “Calculate” button.
- View the results and chart below the calculator.
The pressure drop (ΔP) across a vortex flow meter can be calculated using the following formula:
ΔP = (0.5 * ρ * V² * (1 + 0.15 * (d / D)²)) / (2 * g * sin(θ))
Where:
- ρ = fluid density (kg/m³)
- V = flow velocity (m/s)
- d = vortex finder diameter (m)
- D = pipe diameter (m)
- g = gravitational acceleration (m/s²)
- θ = angle of the vortex finder (degrees)
| Fluid | Density (kg/m³) | Pressure Drop (Pa) |
|---|---|---|
| Water | 1000 | 12345 |
| Air | 1.225 | 123 |
- Always ensure the flow rate and pipe diameter values are accurate for the most reliable results.
- Consider the fluid’s viscosity and temperature, as they can affect the pressure drop.
- Regularly clean and maintain your vortex flow meter to prevent fouling and ensure accurate readings.
