The flow rate of liquid carried on a nylon strand moving from a liquid filled space, through an air filled space, to another liquid filled space was determined from measurements of electrical conductance of the separated liquids. The measurements are consistent with the transmission of a liquid layer on the nylon surface of constant thickness, independent of surface velocity. The layer thickness is low enough that an adsorptive strand can carry adsorbate from a solution at a practical rate. The effective concentration of solution taken from an adsorption chamber by a saturated adsorbent strand is estimated to be at Least 5.8 (lambda/S) times the chamber concentration, where lambda is the chamber length and S the line speed.
