Unlock the power of fluid dynamics with our free Orifice Flow Calculator. Instantly determine the volumetric flow rate through an orifice plate by inputting orifice diameter, pipe diameter, differential pressure, fluid density, and discharge coefficient. Perfect for engineers, students, and anyone needing accurate fluid flow calculations.
Formula:
The calculator uses the simplified orifice flow rate formula:
Q = C ⋅ A ⋅ √(2 ⋅ ΔP / ρ)
Where:
- Q = Volumetric Flow Rate
- C = Discharge Coefficient (dimensionless, typically between 0.6 and 0.9)
- A = Area of the Orifice = π ⋅ (d/2)2
- d = Orifice Diameter
- ΔP = Differential Pressure across the orifice
- ρ = Fluid Density
This formula is fundamental for understanding and designing systems involving flow measurement with orifice plates.
