Single-phase dp using Darcy–Weisbach with Swamee–Jain friction factor.

static calculate_dp(us_l, rho_l, theta, eta_l, d_tube, K, l_cel)[source]

Calcuate the pressure drop due friction and gravity based on various parameters.

Parameters:

  • us_l (float) – superficial liquid flow velocity (m/s)

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

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

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

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

  • K (float) – roughness of 1 cell (m)

  • l_cel (float) – length of 1 cell (m)

Returns:

  • dp_fric (float) – pressure drop due to friction (Pa)

  • dp_grav (float) – pressure drop due to gravity (Pa)
