3. Figure shows layers of soil in a tube that is 100 mm x 100 mm in cross section. After is supplied to maintain a constant head difference of 400 mm across the sample. The hydraulic conductivities of the soils in the direction of flow through them are listed below. Calculate the equivalent k in cm/sec and the rate of water supply in cm³/hr. Soil k (cm/sec) A 1x102 В Зx103 C 4.9x104 Water supply Constant head difference 400 mm

Define particular volume, specific gravity, and viscosity. Include Newton's law of viscosity as well.

A cylindrical soil sample with length = 15cm and diameter = 4cm was taken from a site where a groundwater contamination piume was found. The sample was tested in the lab to determine its hydraulic conductivity. A hydraulic gradient of 0.05 was applied across the sample, and a flow rate of 0.025 cm³/sec was measured. Calculate the hydraulic conductivity of the soil sample using Darcy's law.
