WebbThe Reynolds number needs to be calculated in order to come up with the fanning friction factor: Step 2. Since the relative roughness inside the pipe is assumed to be zero and the Reynolds number confirms that the flow is turbulent, the Darcy friction factor for turbulent flow can be calculated: Step 3.

WebbIn the Hazen-Williams, the C-factor measures the internal pipe roughness and the higher the value, the lower the pressure loss. Standard valves for the C-factor are provided in NFPA 13 and EN 12845 and, for the most part, are identical. As the C-factor is dimensionless, we can use the same C-factor values in the metric and imperial equation. Webb1. Introduction. The pressure drop through common fittings and valves found in fluid piping can be calculated thanks to a friction coefficient K. This coefficient must be determined for every fitting. In pre-project, common values are often sufficient. Usual coefficients are given in the tables below. 2. charlotte irrigation florida
