Explain hydraulic grade line and total energy 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). For ideal or non-viscous fluid there are no losses hence TEL for that fluid is a horizontal line. But for real fluid, it will always slope down ...

Should I Buy a GIA or EGL USA Graded Diamond?

Its not a horrible deal to buy the EGL diamond, just dont expect it to measure up to a GIA one of the same grade - because it will not. Figure that the color grade will be about 2 grades lower and clarity one grade lower than what GIA would grade it. Also, you should expect to pay much less (20% - 35%) for the EGL diamond.

The EGL at Point 1 must equal the EGL at point 2 plus HL from Manning's equation. If the slope of the EGL is greater than the invert slope, it tells you that the Q is greater than the "Full-flow Capacity". If the slope of the EGL is less, then you'll know the Q is below capacity. In the latter case, you should consider decreasing the ...

CE 319F LAB 4

An HGL above a pipe corresponds to positive pressure while an HGL below the centerline means that the pressure is negative. An energy grade line (EGL) shows the variation of the total head. Since the difference between the total head and the piezometric head is the velocity head, the distance between the EGL and the HGL is also the velocity head.
