Abstract
A study has been undertaken to see how a nonuniform surface charge dis tribution affects the pattern of electrolyte flow in a flat capillary greater than the Debye screening length thick in the presence of a con stant pressure drop between its ends. It is shown that the corrections applied to the kinetic coefficients take a minus sign and that for re al system parameters they are 5 - 10% of the values calculated for cap illaries with uniformly charged walls.
