Venturi Meter Calculator

Calculate flow rate from venturi meter: Q = Cd·A₁·A₂·√(2ΔP/ρ)/√(A₁²-A₂²). Typical Cd = 0.98-0.99. Calculate pressure differential needed for a given flow rate measurement range.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Calculate flow rate from venturi meter: Q = Cd·A₁·A₂·√(2ΔP/ρ)/√(A₁²-A₂²). Typical Cd = 0.98-0.99. Calculate pressure differential needed for a given flow rate measurement range

Each component has a specific meaning:

  • Venturi meter: Q = Cd·A₁·A₂·√/√ — The venturi meter: q = cd·a₁·a₂·√/√ recorded for the patient or scenario being assessed.

Note: Interpret the venturi meter result against the clinical thresholds and context described above.

How to Use

Enter the venturi meter: Q = Cd·A₁·A₂·√/√ for the patient or scenario you are assessing. Calculate flow rate from venturi meter: Q = Cd·A₁·A₂·√(2ΔP/ρ)/√(A₁²-A₂²). Typical Cd = 0.98-0.99. Calculate pressure differential needed for a given flow rate measurement range. Use the venturi meter result to inform your clinical assessment.
