The image above represents discharge velocity. To calculate discharge velocity, two essential parameters are needed and these parameters are Rate of Flow (Q) and Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow (A).
The formula for calculating discharge velocity:
v =Â QÂ /Â A
Where:
v = Discharge Velocity
Q = Rate of Flow
A = Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow
Let’s solve an example;
Given that the rate of flow is 11 and the cross-sectional area of soil mass perpendicular to direction of flow is 16. Find the discharge velocity?
This implies that;
Q = Rate of Flow = 11
A = Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow = 16
Rgar is, v = QÂ /Â A
v =Â 11Â /Â 16
v = 0.6875
Therefore, the discharge velocity is 0.6875.
Calculating for Rate of Flow when the Discharge Velocity and the Cross-Sectional Area of Soil Mass Perpendicular to Direction of Flow are Given
Q = vA
Where;
Q = Rate of Flow
v = Discharge Velocity
A = Cross-Sectional Area of Soil Mass Perpendicular to Direction of Flow
Let’s solve an example;
Find the rate of flow when the discharge velocity is 14 and the cross-sectional area of soil mass perpendicular to direction of flow is 4.

This implies that;
v = Discharge Velocity = 14
A = Cross-Sectional Area of Soil Mass Perpendicular to Direction of Flow = 4
That is, Q = vA
Q = 14 x 4
Q = 56
Therefore, the rate of flow is 56.

Calculating the Cross-Sectional Area of Soil Mass Perpendicular to Direction of Flow when the Rate of Flow and the Discharge Velocity are Given
A = Q / v
Where;
A = Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow
v = Discharge Velocity
Q = Rate of Flow
Let’s solve an example;
Find the Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow when the discharge velocity is 3 and the rate of flow is 27.
This implies that;
v = Discharge Velocity = 3
Q = Rate of Flow = 27
That is, A = Q / v
A = 27 / 3
A = 9
Therefore, the cross-sectional area of soil mass perpendicular to direction of flow is 9.
