Choke Single Phase
8 functions
PO.SF.CH.Gas.Pwh
Required upstream pressure for sonic gas flow, [psia].
PO.SF.CH.Gas.Rate
Gas flow rate through choke, [Mscf/d]. Automatically determines sonic or subsonic flow regime.
PO.SF.CH.Gas.Rate.Sonic
Gas flow rate at sonic (critical) conditions, [Mscf/d]. Rate independent of downstream pressure.
PO.SF.CH.Gas.Rcrit
Critical pressure ratio for gas (Pdn/Pup at sonic conditions), [dimensionless]. Flow is sonic when actual ratio <= critical ratio.
PO.SF.CH.Gas.Size
Required choke diameter for sonic gas flow, [inches].
PO.SF.CH.Liq.dP
Pressure drop across choke for liquid flow, [psi].
PO.SF.CH.Liq.Rate
Liquid flow rate through choke, [bbl/d]. Uses Bernoulli equation for incompressible flow.
PO.SF.CH.Liq.Size
Required choke diameter for liquid flow, [inches].
