Sep 18, 2020 The Hydraulic Gradient Line or the Hydraulic Grade Line is defined as a line joining all the liquid levels indicated by piezometers connected to the pipeline throughout. If HGL is above the center of the pipeline, the pressure is positive and HGL is below the center of the pipeline, the pressure is negative .

How to Calculate the Hydraulic Grade Line

How to Calculate the Hydraulic Grade Line

Oct 23, 2013 If the pipe is flowing full, the hydraulic grade line will always be below the energy grade line. In a reservoir i.e. non-moving flow not under pressure the hydraulic grade line will be equal to the energy grade line. A decrease in flow area will result in a decrease in the hydraulic grade line, and vice versa. About Bernie Roseke, P.Eng., PMP
