| Abstract: | On the basis of the predecessors' research and theory, and through an analysis of the geometric relationship between the bed load and the suspension load within the horizontal pipes, an in-depth study was conducted of the relationship between the ratio of the bed load to the suspension load and the mean velocity of flow within the horizontal pipe. Their relational expression was obtained, and the important coefficient K4 was established, thus laying a foundation for establishing both the flow velocity distribution and the critical velocity within the pipes in the future. |
