| Abstract: | In this paper,the method of Ritz,A is used to obtain the exact solution of velocity distribution of steady uniform laminar flow in open channel with trapezoid cross section.Further,tased upon the author's hypothesis about eddy viscosity,the velocity distribution of corresponding turbulent flow is proposed. |
