Seepage Velocity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Seepage velocity represent the actual velocity of a fluid flowing through the void spaces in the soil.

Seepage Velocity formula

(Eq. 1)  \(\large{ v_s = \frac { v A} { A_v}   }\)

(Eq. 2)  \(\large{ v_s = \frac { v} { P}  }\)

Where:

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

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

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

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

\(\large{ P }\) = porosity

Solve for:

\(\large{ A = \frac { v_s   A_v} { v}   }\)

\(\large{ A_v = \frac { v A} { v_s}  }\)

(Eq. 1)  \(\large{ v = \frac { v_s   A_v} { A}  }\)

(Eq. 2)  \(\large{ v = v_s   P  }\)

\(\large{ P = \frac { v} { v_s}  }\)
