In this paper the motion of viscous liquid in a curved pipe bent in the form of a circle is discussed. The cross-section of the pipe is of the form γ=f(θ) having a line of symmetry and the dimension of the section is assumed to be small compared to the radius of the circle traced out by a point within the section. The line of symmetry of the section is taken in the plane of curvature of the pipe in one case and perpendicular to the plane of curvature in the other case. A method of Fourier expansion is applied to find an approximate main flow velocity in the pipe by assuming a uniform stream as the secondary flow in the plane of cross-section. Particular case for a curved pipe of elliptic section of eccentricity 0.25 is worked out.
