Roughness factors
Roughness factors
(OP)
hello,
I would like to have the CHW, roughness (epsilon in Darcy Weibach) and Manning coefficient for a HDP pipe (ex.: Sclairpipe of KHW).
Initial guess would be:
CHW = 150
epsilon = 0.005 mm
n = 0.011
Thanks,

Remember to ask about lifetime changes, heat/cooldown changes, and expected erosion or buildup factors for your chemical/water/air/gas/whatever.
