How to draw a groundwater flow net

WebStep 6: Draw a line that passes through and is perpendicular to each equipotential line. This line marks direction of flow. Step 7: Calculate the hydraulic gradient from the formula, i=dh/dl, where dh is the difference between the most upgradient and most downgradient equipotential lines and dl follows the direction of flow, which is not necessarily a straight … Webthe direction of groundwater flow, and equipotentials (lines of constant head), which show the distribution of potential energy. Flow nets are usually constructed through trial-and …

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. WebThe flow net is shown In the figure. The downstream water level is selected as datum. Between the upstream and downstream equipotentials the total head loss is 4-00 m. In …
