In a falling head permeability test on a soil sample of length 1₁, the head of water in the stand pipe takes 50 seconds to fall from 900mm to 135mm above the tail water level. When another soil sample of length 60mm is placed on the first soil sample, the time taken for the head to fall between the same limits is 150 seconds. The permeameter has a cross-sectional area of 4560 mm² and a stand pipe has an area of 130mm². The permeability of the second soil sample will be

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.
