Webb8 jan. 2024 · Second, Darcy friction factor of Darch-Weisbach equation for a pipe flow is generally provided as Moody chart. There are many emprical equations for Darcy friction factor. e.g. $1/\sqrt{f} = -1.8 \log \left [ \left ( \varepsilon / D /3.7 \right )^{1.11} + 6.9 / \text{Re} \right ]$ Here is the question. General method to consider both the Darcy … WebbThe head loss coefficients of the fittings and their ranges are presented in this report as a function of upstream flow velocity and the Reynolds number. The results of the study show that the K-value of long elbows is smallest for larger pipe fittings and increases as the pipe fitting size decreases. For branching flows in Tees, the
