In the work a model of water vapour and superficial moisture flow in a single capillary is presented taking into account the phenomenon of water vapour adsorption on the capillary walls. Basing on the condition that the capillary pressure gradient is constant the expression, describing a distribution of thickness of liquid film in the capillary, is derived.
