Hydraulic Radius Œ Less than Half Full Flow The hydraulic radius is one of the parameters needed for Manning equation calculations. Equations are available to calculate the hydraulic radius for known pipe diameter and depth of flow. The equations are slightly different depending on whether the pipe is flowing less than half or more than ... WebTo summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system. The flow rate is inversely proportional to the length of the pipe as well as the coefficient of viscosity of the fluid. orby tv services
