Sachdeva LAMBDAs
Sachdeva et al. choke model spanning critical and subcritical flow.
3 lambdas
PO.SF.CH.Sachdeva.Rate.SI(P_up, P_dn, d_choke, GLR, API, SG_gas, WC, T)
Liquid flow rate using Sachdeva (1986) two-phase mechanistic model, [m3/d]. Handles both critical and subcritical flow (SI units).
PO.SF.CH.Sachdeva.Pwh.SI(Ql, d_choke, GLR)
Wellhead pressure using Sachdeva (1986) two-phase model, [kPa]. Iterative solution for target rate (SI units).
PO.SF.CH.Sachdeva.Size.SI(Pwh, Ql, GLR)
Choke diameter using Sachdeva (1986) two-phase model, [cm]. Iterative solution for target rate (SI units).
