Uncover the secrets of fluid dynamics with our Venturi Meter Flow Rate Calculator. Easily determine the volumetric flow rate of a fluid by inputting pipe and throat diameters, pressure difference, fluid density, and the discharge coefficient. Ideal for engineers, students, and anyone working with fluid measurement, this tool simplifies complex Bernoulli's principle calculations.
Formula:
The volumetric flow rate (Q) through a Venturi meter is calculated using a variation of Bernoulli's principle:
Q = C × A2 × √(2 × ΔP / (ρ × (1 - (A2/A1)2)))
Where:
- Q = Volumetric Flow Rate (m³/s)
- C = Discharge Coefficient (dimensionless, typically 0.95 - 0.99)
- A1 = Upstream Pipe Cross-sectional Area (m²)
- A2 = Venturi Throat Cross-sectional Area (m²)
- ΔP = Pressure Difference (P1 - P2) (Pascals, Pa)
- ρ = Fluid Density (kg/m³)
Note: A = π/4 × D², where D is the diameter. The calculator will handle unit conversions and area calculations automatically.
