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) - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T.
Coefficient of permeability - (Measured in Meter per Second) - Coefficient of Permeability of soil describes how easily a liquid will move through the soil.
Hydraulic Gradient - Hydraulic gradient is a specific measurement of liquid pressure above a vertical datum.

STEP 1: Convert Input(s) to Base Unit

Coefficient of permeability: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Hydraulic Gradient: 100 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_mean = k*H --> 0.1*100

Evaluating ... ...

V_mean = 10

STEP 3: Convert Result to Output's Unit

10 Meter per Second --> No Conversion Required

FINAL ANSWER

10 Meter per Second <-- Mean Velocity

(Calculation completed in 00.020 seconds)

Coefficient of Permeability given Velocity

Go Coefficient of permeability = Mean Velocity/Hydraulic Gradient

Hydraulic Gradient given Velocity

Go Hydraulic Gradient = Mean Velocity/Coefficient of permeability

Mean Velocity using Darcy's Law

Go Mean Velocity = Coefficient of permeability*Hydraulic Gradient

Mean Velocity using Darcy's Law Formula

Mean Velocity = Coefficient of permeability*Hydraulic Gradient
V_mean = k*H

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.
