2020-3-26 · Energy Grade Line (EGL) Energy grade line is always above the hydraulic grade line by an amount equal to the velocity head. Thus, the distance of energy gradient above the datum plane is always (v 2 /2g + p/ γ + z). Energy grade line therefore is the graphical representation of the total energy of flow. Characteristics of EGL

Hydraulic and Energy Grade Lines

2020-3-27 · In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance ...

Kinetic Energy Correction Factor

hydraulic grade line (HGL) The surface or profile of water flowing in an open channel or a pipe flowing partially full. If a pipe is under pressure, the hydraulic grade line is that level water would rise to in a small, vertical tube connected to the pipe. Also see energy grade line.

What is energy? The ability to do work or cause change. Work is the application of a force through a distance. (Ask students for examples, such as moving a box across the room, sweeping, etc.) Force can put matter into motion or stop it if it is already moving. Motion is a change in position of an object with time. To do work, energy is needed.
