"Web5. FLOW OF WATER THROUGH SOIL 5.1 FLOW OF WATER IN A PIPE The flow of water through a rough open pipe may be expressed by means of the Darcy-Weisbach resistance equation ∆h = f L D v2 2g (5.1) in which _h is the head loss over a length L of pipe of diameter D. The average velocity of flow is v. f is a measure of pipe resistance. " - Flow nets in geotechnical engineering
