# Groundwater Velocity Calculator, Formula, Groundwater Velocity Calculation

## Groundwater Velocity Calculator:>

Enter the values of Horizondal Conductivity, Horizondal Hydraulic Gradient & Effective porosity to determine the value of Groundwater Velocity Vgw(m/s) .

 Enter Horizondal Conductivity: Enter Horizondal Hydraulic Gradient: Enter Effective Porosity: Result – Groundwater Velocity: m/s

## Groundwater Velocity Formula:

The Groundwater Velocity Vgw(m/s) in meter per second is equal to the Horizondal Conductivity K into multiply the Horizondal Hydraulic Gradient L is Divided by the Effective porosity n.

The Formula of Groundwater Velocity can be writtern as,

Vgw(m/s) = K * L / n

Here,

Vgw(m/s) = Groundwater Velocity in meter per second

K = Horizondal Conductivity

n = Effective porosity

### Calculation For Groundwater Velocity:

1)Calculate the Groundwater Velocity and given for Horizondal Conductivity = 10 , Horizondal Hydraulic Gradient = 5 , Effective porosity = 2.

Vgw = K * L / n

Vgw = 10 * 5 / 2

Vgw = 25m/s.

2)Calculate the Effective porosity and given for Horizondal Conductivity = 10 , Horizondal Hydraulic Gradient = 5 , Groundwater Velocity = 25m/s.
