The image above represents entrance velocity.

To compute for entrance velocity, one essential parameters are needed and these parameters are **Hydraulic Conductivity (k _{i}).**

The formula for calculating entrance velocity:

V_{e} = k_{i}

Where:

V_{e} = Entrance Velocity

k_{i} = 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} = k_{i}

V_{e} = 8

Therefore, the **entrance velocity **is **8.**

Nickzom Calculator – **The Calculator Encyclopedia** is capable of calculating the entrance velocity.
