Darcy friction factor for copper pipe
WebII. The Friction Factor This brings us to the most interesting and complex part of the equation, the friction factor. The first complication that arises is that there are two common friction factor definitions in standard usage : the Fanning and the Darcy-Weisbach.. In the nineteenth century, two groups approached the fluid flow WebOmission of frequency-dependent hydraulic resistance (skin friction) during modelling of the water hammer phenomenon is unacceptable. This resistance plays a major role when the transient liquid flow occurs in rigid-walled pipes (steel, copper, etc.). In the literature, there are at least two different modelling approaches to skin friction. The first group consists …
