3 lambdas
PO.VFP.HagedornBrown.dPdL.SI(Ql, Qg, P, Rho_l, Ul, Bl, Rho_g, Ug, Bg, IFT_gl, Rs, pipe_ID, pipe_roughness)
Calculates pressure gradient for multiphase pipe flow using Hagedorn and Brown (1965) correlation with Griffith modification, [kPa/m]. Developed for vertical, upward flow and recommended only for near-vertical wellbores (SI units).
PO.VFP.HagedornBrown.Pout.SI(Ql, Qg, P_in, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates outlet pipe pressure using Hagedorn and Brown (1965), [kPa]. For vertical/near-vertical wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
PO.VFP.HagedornBrown.Pin.SI(Ql, Qg, P_out, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates inlet pipe pressure using Hagedorn and Brown (1965), [kPa]. For vertical/near-vertical wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
