The study addresses viscous and Joule losses that accompany an electro-osmotic process in water and in air. A physical model was presented by a cylindrical capillary with open ends, which was placed in water or air and filled with the fluid that surrounds it. We have considered a model of the viscous incompressible fluid. Validity of such an approximation is noted. It is demonstrated that the electro-osmotic losses have a number of specific features as compared to other processes of motion of a fluid in porous media. The said losses in both the media have been calculated. Keywords: electrokinetic emitters, a fluid-filled capillary, a viscous incompressible fluid, viscous losses, Joule losses, comparative estimation of losses in air and the liquid medium.
