Use this free Coefficient of Discharge Calculator to accurately determine the Cd value for various fluid flow devices like orifices, nozzles, and venturi meters. Understand the efficiency of your flow system by inputting actual flow rate, area, pressure drop, and fluid density. Simplify complex fluid dynamics calculations instantly.
Formula:
The Coefficient of Discharge (Cd) is calculated using the following formula:
Cd = Qactual / (A × √(2 × ΔP / ρ))
- Qactual: Actual Volumetric Flow Rate (m³/s)
- A: Cross-sectional Area of Orifice/Nozzle (m²)
- ΔP: Pressure Drop across Orifice/Nozzle (Pa)
- ρ: Fluid Density (kg/m³)
