# Discharge Velocity

on . Posted in Geotechnical Engineering

Discharge velocity, abbreviated as q, is the rate of water through a porous medium per unit of total area perpendicular to the direction of flow.

## Discharge Velocity formula

$$\large{ q = V_t \; A_c }$$
Symbol English Metric
$$\large{ q }$$ = discharge velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
$$\large{ A_c }$$ = area cross-section $$\large{ft^2}$$ $$\large{m^2}$$
$$\large{ V_t }$$ = total volume of soil $$\large{ft^3}$$ $$\large{m^3}$$
