Question
A test is set-up as shown in the figure below. A cylindrical mold 4" in diameter is filled with silt to a height H1= 0.28 ft whose coefficient of permeability is 6.28x10^-4 ft/min.
A second coaxial mold, placed on top of the silt inside the first mold, has an inside diameter of 1.50 and height of H2= 0.35 ft. Its thickness is negligible. The inside of this second mold is filled with the same
silt, but the annular ring outside is filled with sand whose coefficient of permeability is 3.75x10-3 ft/min.
The test set-up is a permeameter of constant head. Water is placed in the mold and maintained at a level h = 1.45 ft above the level of the outlet.
