Explanation: HGL is obtained by plotting piezometric head at various points along the axis of the pipe.
Hp = P ⁄ γ + z
where Hp is the piezometric head, P ⁄ γ is the pressure head and z is the potential head.
Hp = P ⁄ γ + z
where Hp is the piezometric head, P ⁄ γ is the pressure head and z is the potential head.

Hydraulic gradient line takes into consideration potential and pressure heads only.
• Definition of hydraulic gradient line:
The hydraulic gradient line (HGL) is a line that represents the total head at any point in a fluid flow system, including the potential and pressure heads.
• The components of total head in a fluid flow system:
Total head in a fluid flow system is made up of three components:
- Potential head (z): This is the height above a reference plane (datum) where the fluid is at rest.
- Kinetic head (v²/2g): This is the energy associated with the velocity of the fluid.
- Pressure head (P/ρg): This is the energy associated with the pressure of the fluid.
• The hydraulic gradient line takes into account potential and pressure heads only:
The hydraulic gradient line takes into account only the potential and pressure heads, and not the kinetic head. This is because the kinetic head is typically small compared to the potential and pressure heads in most fluid flow systems.
• Importance of the hydraulic gradient line:
The hydraulic gradient line is an important tool in fluid mechanics, as it allows engineers to determine the total head at any point in a fluid flow system. This information is critical for designing and analyzing fluid flow systems, such as pipelines, pumps, and water treatment plants.
