Simple choke CV question
Simple choke CV question
(OP)
Choke CVs are normally quoted in units of gal/min/psi ... what type of gallons? Imperial or US?
Yet another reason to switch to metric ...

RE: Simple choke CV question
North America O&G is US gallons.
The best is for barrels UK/US, wine/dry/frderal/liquid/petroleum
Man! I love the metric system!!

RE: Simple choke CV question
The engineering toolbox states us galons per minute. Cv of one passes one US gallon per minute per psi drop.
The flow capacity coefficient for SI units is Kv. See IEC 60534-1 or ISA 75.01.01. Table 1 in ISA 75 reflects various constants for the sizing equations for both Kv and Cv. People who spell colour instead of color use Kv.

Us Canucks speak out of both sides of our mouth......wait I mean we say 'colour', 'aboot' and Cv all at the same time.

bara, bard, barg
kg(f)/cm^2 (a), kg(f)/cm^2 (d), kg(f)/cm^2 (g)
kPa(a), kPa(d), kPa(g)
cm H2O, or maybe
Torr
Lots of great choices.

But even most Germans would prefer the dimensionless k to Kv i think
