Hydraulic Energy Line Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hydraulic energy line = Pressure Head+Datum Head
HEL = h_p+Z
This formula uses 3 Variables

Variables Used

Hydraulic energy line - (Measured in Meter) - Hydraulic energy line is defined as a line joining all the liquid levels indicated by piezometers connected to the pipeline throughout.
Pressure Head - (Measured in Meter) - Pressure Head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container.
Datum Head - (Measured in Meter) - Datum head is defined as the head owned by the fluid due to the height above the datum.

STEP 1: Convert Input(s) to Base Unit

Pressure Head: 12 Meter --> 12 Meter No Conversion Required
Datum Head: 120 Meter --> 120 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

HEL = h_p+Z --> 12+120

Evaluating ... ...

HEL = 132

STEP 3: Convert Result to Output's Unit

132 Meter --> No Conversion Required

FINAL ANSWER

132 Meter <-- Hydraulic energy line

What is hydraulic grade line and energy line?

The distance from the centerline of the pipe to the HGL is the pressure head. 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.

What do you mean by hydraulic gradient line?

: a line joining the points of highest elevation of water in a series of vertical open pipes rising from a pipeline in which water flows under pressure.
