Single-Phase Chokes LAMBDAs
Gas and liquid flow through a choke in single-phase service.
7 lambdas
PO.SF.CH.Gas.Rate.SI(P_up, P_dn, d_choke, SG_gas, T, Cd, k)
Gas flow rate through choke, [sm3/d]. Automatically determines sonic or subsonic flow regime (SI units).
PO.SF.CH.Gas.Rate.Sonic.SI(P_up, d_choke, SG_gas, T, Cd, k)
Gas flow rate at sonic (critical) conditions, [sm3/d]. Rate independent of downstream pressure (SI units).
PO.SF.CH.Gas.Pwh.SI(Qg, d_choke, SG_gas, T, Cd, k)
Required upstream pressure for sonic gas flow, [kPa] (SI units).
PO.SF.CH.Gas.Size.SI(Qg, P_up, SG_gas, T, Cd, k)
Required choke diameter for sonic gas flow, [cm] (SI units).
PO.SF.CH.Liq.Rate.SI(d_choke, dP, Rho_l, Cd)
Liquid flow rate through choke, [m3/d]. Uses Bernoulli equation for incompressible flow (SI units).
PO.SF.CH.Liq.dP.SI(d_choke, Ql, Rho_l, Cd)
Pressure drop across choke for liquid flow, [kPa] (SI units).
PO.SF.CH.Liq.Size.SI(Ql, dP, Rho_l, Cd)
Required choke diameter for liquid flow, [cm] (SI units).
