Laminar flows in convergent or divergent pipes were treated. To find the approximate solution, it is assumed that the streamfunction ψ can be expanded in the form [numerical formula] being the function of θ alone. In this paper ψ_<t's> were solved taking into account to the order of ψ_2,and the velocity components V_r, V_θ and the pressure distribution in the pipe were found. When the angle of the vertex of the cone is large, it wiss assumed that the boundary layer grows along the wall of the cone. For the convergent flow, the boundary layer equation have been solved and the local frictional coefficient and the velocity distribution in the boundary layer have been found.
