Fully developed laminar flow in a curved square duct rotating about a center of curvature is investigated by similarity arguments, computational studies and use of experimental data. Similarity arguments suggest that the flow characteristics are governed by four parameters : the Dean number K<SUB>LC</SUB>, the body force ratio F, the curvature parameter λ and the Rossby number Ro. By using the computed flow patterns, the flow structure is elucidated for a wide range of these parameters. The computational results for the friction factor are compared with the practical formula for circular pipes and with various experimental data. It is proven that the formula for circular pipes can be applied to flow in square pipes.
