Webb20 nov. 2006 · Assuming no re-coalescence of bubbles, the gas-flux conservation equation leads to (14) ε G V P-U sg = ε GB (V P-V GB). We could not find any literature reporting direct measurements of the mean gas velocity in the liquid slug. However, using Eq. (14) the mean gas velocity in the liquid slug can be obtained by (15) V GB = V P-ε G V P-U sg ε … WebbThe Bouwer-Rice slug test is designed to estimate the hydraulic conductivity of an aquifer.
