WebA longitudinal profile of the elevation of the specific energy head is called the energy grade line, or the total-head line A longitudinal profile of the water surface is called the hydraulic grade line. The vertical distance between these profiles at any point equals the velocity head at that point. Share this post Kanwarjot Singh http://www.owp.csus.edu/glossary/energy-grade-line.php
WebA special energy form is commonly used in hydraulics in which the channel invert is selected as the reference Z elevation (figure 2-3c). Thus, Z drops out, and energy is the sum of …
WebDec 30, 2024 · Definition: Total Energy Line or Energy Grade Line i.e. TEL is defined as a line joining the points representing the total head.
