Hydraulic Gradient Line (H.G.L):
It is defined as the line which gives the sum of pressure head (P/ρg) and datum (z).
\(H.G.L\;= \frac{P}{{ρ g}} + z\)
∴ H.G.L line lies below T.E.L with a difference of Velocity head (V2/2g).
In order to avoid vaporization in the pipeline, the pipeline over the ridge is laid in such a way that it is not more than 6.4 m above the hydraulic gradient.
