What is hydraulic gradient line?
Understand the Problem
The question is asking for an explanation of the hydraulic gradient line, which is a concept in fluid mechanics and civil engineering. The hydraulic gradient line represents the change in hydraulic head per unit distance in a given direction in a fluid flow system. It is often used to analyze pressure and energy losses in pipelines and open channels.
Answer
A hydraulic gradient line (HGL) joins the points representing the piezometric head at various cross-sections of a pipe.
The final answer is: A hydraulic gradient line (HGL) is the line joining the points representing the values of piezometric head (pressure head + elevation head) at various cross-sections of a pipe in pipe flow.
