The pressure drop/flow rate equation for non‐Newtonian fluid flow in channels of irregular cross‐section is determined theoretically by two numerical methods. Two representative non‐Newtonian fluid models, the Ellis and the Herschel‐Bulkley models, have been studied for several commonly encountered non‐circular channels. The empirical methods proposed by Kozicki, et al , and Miller have been analyzed. The validity of their methods is discussed.
