Volumetric Flow vs. Pressure Drop Curve - Flares

[neerac]

Does anyone know where I would be able to find a volumetric flow vs. pressure drop curve for Flare lines and Flare tips?? I want to verify that the P drops in my flare and flare tips are reasonable.

neerac,

Each time I needed it I got the original hydraulic calcs (flow rate, composition and pressure drop) for the flare tip and seal from the flare vendor (Calidus and AirOil FlareGas I think).

The pressure drop through the riser+piping+header you can calculate yourself.
