WebTotal energy per unit weight at 1 = Total energy per unit weight at 2 In formulating Equ. (4.6), it has been assumed that no energy has been supplied to or taken from the fluid between points 1 and 2. Energy could have been supplied by introducing a pump; equally, energy could have been lost by doing work against friction in a machine

Energy and Hydraulic Grade Line - Engineering ToolBox

WebThe hydraulic gradient is the difference in total hydraulic head per unit distance. What is total energy line and hydraulic gradient line? Definition: Total Energy Line or Energy Grade Line i.e. TEL is defined as a line joining the points representing the total head. It means the total energy line represents the sum of (P/γ + V²/2g + Z). http://www.watertraining.ca/courses/wt/328/328a4.html other term for reviewer

WebHydraulic Grade Line Hydraulic grade line is a hypothetical line used to indicate the relative elevation of the total energy head (of the water) at any point in the pipeline. The concepts of the hydraulic grade line are illustrated below. WebEnergy Grade Line. The Energy Grade Line, also called the Energy Line (EL), is a plot of the Bernoulli equation or the sum of three terms in the work-energy equation. The EL is equal to the sum of the fluid's velocity head, … WebA turbine in the run reduces the energy line and a pump or admirer in the line increases the energy line.
