The image above represents entrance velocity.

To calculate entrance velocity, one essential parameter is needed, and this parameter is **Hydraulic Conductivity (k _{i}).**

The formula for calculating entrance velocity:

V_{e}Â = k_{i}

Where:

V_{e}Â = Entrance Velocity

k_{i}Â = Hydraulic Conductivity

Let’s solve an example;

Find the entrance velocity when the hydraulic conductivity is 8.\

This implies that;

k_{i} = Hydraulic Conductivity = 8

V_{e}Â = k_{i}

V_{e}Â = 8

Therefore, theÂ **entrance velocityÂ **isÂ **8.**
