Question

A permeameter setup is shown in Figure 1. A cylindrical mold 4” in diameter is filled with silt to H1 = 0.20 ft, whose coefficient of permeability k1 = 2.36 × 10^-4 ft/min. A second coaxial mold (negligible thickness) is placed on top of the first mold whose inside diameter d = 1.5” and whose H2 = 0.30 ft and is filled with silt, but the annular ring outside the small tube is filled with sand whose coefficient of permeability is k2 = 2.7 × 10^-3 ft/min. The test set-up is a permeameter of constant head and maintained at a level h = 1.25 ft above the level of the outlet. Find the ff: • Equivalent coefficient of permeability (in/s) • Total flow of water (ft^3/day) • Total amount of water (in^3) percolated after 75 min

1. A permeameter setup is shown in Figure 1. A cylindrical mold 4" in diameter is filled with
silt to H₁ = 0.20 ft, whose coefficient of permeability k₁ = 2.36 x 10-4 ft/min. A second
coaxial mold (negligible thickness) is placed on top of the first mold whose inside diameter
d = 1.5" and whose H₂ = 0.30 ft and is filled with silt, but the annular ring outside the small
tube is filled with sand whose coefficient of permeability is k₂ = 2.7 x 10³ ft/min. The test
set-up is a permeameter of constant head and maintained at a level h = 1.25 ft above the
level of the outlet. Find the ff:
