The effect of wall roughness on laminar flows may be important in micro sized channels though it is often neglected in macro sized flow geometries. Based on entropy production considerations we show how its influence can be determined theoretically. It is also discussed how different ways to define the actual wall location influence the pressure drop results in terms of a Poiseuille number. Copyright © 2007 by ASME.
