  • rho_g (float) – gas density (kg/m3)

  • rho_l (float) – liquid density (kg/m3)

  • theta (float) – Inclination of 1 cell (rad)

  • eta_g (float) – gas viscosity (Pa s)

  • eta_l (float) – liquid vicosity (Pa s)

  • sigma (float) – surface tension (N/m)

  • d_tube (float) – well diamater of 1 cell (m)
