DAY 40: HYDRAULICS 5 FLOW IN OPEN CHANNELS From Darcy Weisbach formula, h = fL D ∙ v 2 2g From pipes, D = 4R SL = fL 4R ∙ v 2 2g v 2 = 8g f RS v = 8g f RS Let C = 8g f , v = C RS Q = AC RS ฑ HL Length of reach, L No man ever steps in the same river twice, for it's not the same river and he's not the same man.
