In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. Currently, there is no formula more accurate or universally applicable than the Darcy-Weisbach supplemented by the Moody diagram or Colebrook equation.
Webchezy’s constant (C) is dimensionless, it can be determined by different formulas. Here we see how it will be determined through the bazin formula, C = 157.6 1.81+ K √m C = 157.6 1.81 + K m. Here K= basin constant. m= hydraulic mean depth/ radius. here K depends on the roughness of the channel surface.
