A sand cone test was conducted in the field. The mass of wet soil excavated from the hole is 3668.3g with a moisture content of 17.2%. Before and after the test, the sand cone apparatus weighed 10154.0g and 5749.4g. The cone can contain 1680g of Ottawa Sand (ρ=1.353g/cc). If the maximum dry density of the soil is 1.702g/cc, calculate the relative compaction.

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.
