Hydraulic gradient ( \(i\) ) (dimensionless number) is the change in height (pressure) to length.

Hydraulic Gradient FORMULA

\(\large{ i = \frac { h_1 \;-\; h_2} { l}  }\)         

Where:

\(\large{ i }\) = hydraulic gradient

\(\large{ h_1 }\) = pressure head at point 1

\(\large{ h_2 }\) = pressure head at point 2

\(\large{ l }\) = length of column

Solve for:

\(\large{ h_1 = i   l \;+\; h_2  }\)

\(\large{ h_2 = h_1 \;-\; i  l   }\)

\(\large{ l =  \frac { h_1 \;-\; h_2} { i}    }\)
