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.

If all of the above rules are to apply, we can immediately see that the flow net must consist of straight equipotential and flowlines (Fig.3). Figure 3 – Flow net for a simple flow system. Notice that all squares formed by equipotential and flowlines are curvilinear.

WebIn Fig. 7.8 a, there is no flow and the water is static. In Figs. 7.8 b, flow takes place due to a head difference of hL across the specimen, and the flow is upwards through the specimen. In Fig. 7.8 c, the flow through the specimen is downwards, again due to a head difference of hL. When there is flow, the hydraulic gradient i is given by hL/L.
