Hydraulic and Energy Grades
The energy grade is the sum of the hydraulic grade and the velocity head (V2/2g). This is the height to which a column of water would rise in a pitot tube. The plot of the energy grade in a profile is often referred to as the energy grade line, or EGL. At a lake or reservoir, where the velocity is essentially zero, the EGL is equal to the HGL ...

Hydraulic Design of Water Distribution Storage Tanks
There are several key considerations in the hydraulic design of water storage tanks. Equalization is the primary purpose for constructing water distribution storage tanks. Water utilities like to operate treatment plants at a relatively constant rate, and wells and pumping stations generally work best when pumped at a steady rate.
