Mean Velocity using Darcy's Law Solution

Follow our step by step solution on how to calculate Mean Velocity using Darcy's Law?

FIRST Step Consider the formula

V mean = k \cdot H

Next Step Substitute values of Variables

∴

V mean = 10cm/s \cdot 100

Next Step Convert Units

∴

V mean = 0.1m/s \cdot 100

Next Step Prepare to Evaluate

∴

V mean = 0.1 \cdot 100

LAST Step Evaluate

∴

V mean = 10m/s
