(a)

Answer to Problem 7.9P
The absolute permeability of the soil is
Explanation of Solution
Given information:
The length of the soil sample L is 400 mm.
The area of the sample A is
The diameter of the standpipe (d) is 11 mm.
The head difference
The head difference
The unit weight of water
The dynamic viscosity of water
Calculation:
Determine the area of the standpipe a using the relation.
Substitute 11 mm for d.
Determine the hydraulic conductivity k using the relation.
Substitute
Determine the absolute permeability of the soil using the relation.
Substitute
Therefore, the absolute permeability of the soil is
