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.

Consider that a 58.7 gram sample of dry soil is used in making a mechanical analysis by using the hydrometer method. The laboratory was held at a constant temperature of 20 C (68 F). The 40 s hydrometer reading was found to be 32.5 and the 8 hr hydrometer reading was 15.5. The percentage of sand in this soil sample is (note, a 58.7 gram sample is used here): Your Answer: Answer units

A direct shear test is performed on a soil sample with two different loads. In the first test, a normal stress of 55kPa is applied and the soil fails at a shear stress of 35kPa. In the second test, the soil failed at shear stress of 47kPa when a normal stress of 75 kPa was applied. Determine the values of internal friction angle and cohesion of the given soil sample.
