Coefficient Permeability of Soil A falling head permeability test is conducted on silty soil. The sample diameter is 10.0 cm and its length or thickness is 7.8 cm. The diameter of the standpipe is 6.0 mm. The head at the start of the test is 47.8 cm. The test lasts 8.5 min and the head falls to 22.6 cm. Find the coefficient of permeability of this soil in cm/s? Provide step by step solution.

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.
