Formula & Methodology
The flow rate (Q) in an orifice meter can be calculated using the following formula:
Q = C * A * sqrt(2 * ΔP / ρ)
Where:
- C is the discharge coefficient (dimensionless)
- A is the area of the orifice (m²)
- ΔP is the pressure drop across the orifice (Pa)
- ρ is the fluid density (kg/m³)
