PO.VFP.HasanKabir.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 using Hasan-Kabir (1988) mechanistic model, [kPa/m]. For deviated wells and annular geometry (SI units).
PO.VFP.HasanKabir.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 Hasan-Kabir (1988), [kPa]. For deviated wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
PO.VFP.HasanKabir.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 Hasan-Kabir (1988), [kPa]. For deviated wells. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
