AB The Darcy flow in a tube with three-dimensional wall roughness is studied. Three types of bumps or roughness geometry are considered. The problem is solved by the perturbation method, assuming the amplitude of the bumps is small compared to the mean tube radius. For a given mean pressure gradient in a tube of given mean radius, the flow rate may increase or decrease depending on the roughness geometry.
