The image above represents discharge velocity. To calculate discharge velocity, two essential parameters are needed and these parameters are **Rate of Flow (Q)Â **andÂ **Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow (A).**

The formula for calculating discharge velocity:

v =Â ^{Q}Â /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 = ^{Q}Â /Â _{A}

v =Â ^{11}Â /Â _{16}

v = 0.6875

Therefore, theÂ **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, theÂ **rate of flowÂ **isÂ **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, theÂ **cross-sectional area of soil mass perpendicular to direction of flowÂ **isÂ **9.**
