Groundwater Velocity Calculator
Enter the values of Horizondal Conductivity, Horizondal Hydraulic Gradient & Effective porosity to determine the value of Groundwater Velocity Vgw(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
L = Horizondal Hydraulic Gradient
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.
Answer
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.
Answer
Vgw = K * L / n
25 = 10 * 5 / n
n = 2.
