The torque effect of low twist cholesterics on capillary axial flow between coaxial cylinders has been studied as a function of flow rate and pitch. The motion of disclinations and textures as well as the flow-induced transformation into new textures were separately studied. A model of simultaneous translational flow (of Poiseuille type) and permeation describes the experimental relations in a quantitative way. Maximum permeation of about 2 per cent of total flow was found for a pitch being near the thickness of capillary layer.
