摘要: The calculation of flow splitting in froths and foams is needy several instances the industrial field. liquid can be calculated terms viscosity, surface tension, syneresis specific rate interstitial pulp, considering that, under equilibrium during air sparging, drainage matches upward caused by bubbles rising. This works treats on determination these properties, using very simple experimental setup.
