Calculating Friction Loss Darcy-Weisbach Formula vs. Hazen ...
www.vikinggroupinc.comAntoine de Chezy. In Chezy’s formula, friction loss is calculated by using a coefficient reflecting the roughness of the pipe, the internal hydraulic radius of the pipe and the hydraulic slope, which is the friction loss per unit length of pipe. The formula is expressed as: v= c√rs where c= coefficient for pipe roughness r= internal ...
