Weisbach first proposed the equation we now know as the Darcy-Weisbach formula or Darcy-Weisbach equation:h f = f (L/D) x (v2/2g)where:h f = head loss (m)f = friction factor L = length of pipe work (m)d = inner diameter of pip e work (m)v = velocity of fluid (m/s)g ...
‘C’ had to be determined experimentally. The Darcy-Weisbach equation Weisbach first proposed the equation we now know as the Darcy-Weisbach formula or Darcy-Weisbach equation: h f = f (L/D) x (v 2 /2g) where: h f = head loss (m) f = friction factor L = length of pipe work ...
