Seepage Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Seepage velocity, abbreviated as \(v_s\), represent the actual velocity of a fluid flowing through the void spaces in the soil.

Seepage Velocity formula

\(\large{ v_s = \frac { v \; A_c} { A_v}   }\)

\(\large{ v_s = \frac { v} { P}  }\)

Where:

\(\large{ v_s }\) = seepage velocity

\(\large{ A_c }\) = area cross-section of flow

\(\large{ A_v }\) = area cross-section of voids

\(\large{ v }\) = darcy velocity or flux

\(\large{ P }\) = porosity

Solve for:

\(\large{ A_c = \frac { v_s \;  A_v} { v}   }\)

\(\large{ A_v = \frac { v \; A_c} { v_s}  }\)

\(\large{ v = \frac { v_s \;  A_v} { A_c}  }\)

\(\large{ v = v_s  \; P  }\)

\(\large{ P = \frac { v} { v_s}  }\)
