# Seepage Velocity

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

$$\large{ v_s = \frac{ v \; A_c}{ A_v} }$$
Symbol English Metric
$$\large{ v_s }$$ = seepage velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
$$\large{ A_c }$$ = area cross-section of flow $$\large{ft^2}$$ $$\large{m^2}$$
$$\large{ A_v }$$ = area cross-section of voids $$\large{ft^2}$$ $$\large{m^2}$$
$$\large{ v }$$ = darcy velocity or flux $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
