he fully-developed flow of incompressible fluid through the curved pipe with the elliptic cross section has been investigated analytically and experiment~1ly. The velocity profiles of the main flow and the flow pattern of the secondary flow are made clear by the numerical analysis. Also, the studies are conducted on the effects of the shape of the cross section upon the friction coefficient, important in the industrial engineering. The experiments are executed by flowing water through the curved pipe with the elliptic cross section. The experimental results of the pressure drop are compared with the analytical results. The approximate expression of the friction coefficient, which is taken account of the aspect ratio and the tube pitch, is presented on the basis of the analytical and experimental results.
