Popis:	This paper considers electrification of a liquid when the diffusion boundary-layer thickness and the liquid Debye radius are of the same order of magnitude and the effect of the electric field developed on ion motion is significant. Cases of complete and slight dissociation are considered. It is shown that in each of the cases considered there exist dimensionless variables in which in the zeroth approximation with respect to the parameter for the tube radius the dependence of maximum electrification current on problem parameters is describable by a universal curve. The form of this curve is obtained numerically for each case. The dependence of maximum electrification current on tube dimensions, liquid properties, and flow parameters is analyzed. The limits of applicability of the solution obtained is evaluated.
