3 lambdas
PO.VFP.BeggsBrill.dPdL.SI(Ql, Qg, P, Rho_l, Ul, Bl, Rho_g, Ug, Bg, IFT_gl, Rs, pipe_ID, pipe_roughness, pipe_angle)
Calculates pressure gradient for multiphase pipe flow using Beggs and Brill (1973) correlation, [kPa/m]. Can be applied for any wellbore inclination and flow direction (SI units).
PO.VFP.BeggsBrill.Pout.SI(Ql, Qg, P_in, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness, pipe_angle)
Calculates outlet pipe pressure using Beggs and Brill (1973), [kPa]. For any wellbore inclination. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
PO.VFP.BeggsBrill.Pin.SI(Ql, Qg, P_out, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness, pipe_angle)
Calculates inlet pipe pressure using Beggs and Brill (1973), [kPa]. For any wellbore inclination. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
