Mean Velocity using Darcy's Law Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Velocity = Coefficient of Permeability*Hydraulic Gradient
V_mean = k*H
This formula uses 3 Variables

Variables Used

Mean Velocity - (Measured in Meter per Second) - The Mean Velocity refers to the average rate at which an object or fluid moves over a given time interval.
Coefficient of Permeability - (Measured in Meter per Second) - The Coefficient of Permeability refers to the rate of water flow under laminar conditions through a unit cross-sectional area of a porous medium.
Hydraulic Gradient - The Hydraulic Gradient refers to the change in water level per unit distance along the direction of maximum head decrease.

What is Hydraulic Gradient?

Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance of a piezometer.

What is Coefficient of Permeability?

Coefficient of permeability of a soil describes how easily a liquid will move through a soil. It is also commonly referred to as the hydraulic conductivity of a soil. This factor can be affected by the viscosity, or thickness(fluidity) of a liquid and its density.

How to Calculate Mean Velocity using Darcy's Law?

Mean Velocity using Darcy's Law calculator uses Mean Velocity = Coefficient of Permeability*Hydraulic Gradient to calculate the Mean Velocity, The Mean Velocity using Darcy's Law formula is defined as the average velocity of a fluid or object over a given period of time or distance which is directly proportional to both the hydraulic gradient and the coefficient of permeability. Mean Velocity is denoted by V_mean symbol.
