Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.

Question

The given values are as follows:

The specimen's e=0.46

length of soil specimen=450mm

constant head difference=700mm

Water collected in 3 minutes =3.54x10^-4 m³

Area=2.26x10^-3 m²

1) Find the coefficient of permeability (Ans. 2.012 m/hr)

2) Find the discharge velocity (Ans. 0.052 m/min)

3) Find the interstitial velocity (Ans. 0.165 m/min)
