PVC Resistance Coefficient, K - Pipelines, Piping and Fluid …

6/12/2004· I agree with BobPE - the material will not have a significant effect on the K value. The K value is the nuer of velocity heads lost and is not influenced by the friction factor. This is sometimes confusing when using the Crane 410 procedures. The way Crane

Darcy friction factor formulae - Wikipedia

In fluid dynamics, the Darcy friction factor formulae are equations that allow the calculation of the Darcy friction factor, a dimensionless quantity used in the Darcy–Weisbach equation, for the description of friction losses in pipe flow as well as open-channel flow.
