Description
Summary:Most of the equations that have been developed for relating velocity of a stream in a partly filled pipe to the slope and size of the stream use hydraulic radius (R) as the parameter for Size. The equations using this parameter are poor representations of flow behavior when comparing different relative depths of flow, as Camp pointed out for the case of the Manning equation. If quantity of flow (Q) is used as a parameter for size, an equation is obtained which is very simple to use and which represents flow velocities better than do any of the conventional equations.
