| Abstract: | In this paper, Velocity distribution and flowrate formulas of shear flow across the trapezium pipe are direved from separate variable and the figure of the Velocity's shape across the section is shown, which is drawn by a computer.The paper is a good example and an exact solution of using the Navier-stokes equations for such a problem, which is instructive for solving such problem on other non-circular pipes as well as solving such practical problems on engineering. |
