What is the plasticity index of the soil? c. Determine the liquidity index of the soil when the in situmoisture content is 26%

A soil sample has a void ratio of 0.67. Find the ratio between discharge velocity and seepage velocity within the soil.

I need help on this soil problem. Thank YOU calculate the hydraulic conductivity, k, of this sediment after solving for it from the following relationship (where r and μ are the specific weight of water and the dynamic viscosity of water which is about 0.001 Pa s at 20 degrees C):  K= 1.08x10^-10 m/s   or  1.08x10^-3 m/yr

Sketch and explain the relationship between hydraulic conductivity and hydraulicgradient. If the gradient used in the laboratory is too high, will the measured hydraulicconductivity be higher or lower than the hydraulic conductivity expected in the field?Assume that the laboratory test is conducted on a specimen large enough to berepresentative of field conditions

The hydraulic conductivity of a soil sample (3.4 x 10-4 cm/s) has been determined via a permeability test. The water temperature was 28°C at the time of experiment. What is the hydraulic conductivity of the sample at the standard temperature of 20°C?

Problem 4. A 1-m³ sample of moist soil weighs 2000 kg. The water content is 10%. Assume is 2.70 Mg/m³. With this information, fill in all blanks in the phase diagram below. V₁ = V₂ Vw Air Water- Soil M₂ Ms M₁ =

Problem 1: During Atterberg limit tests in the soil mechanics laboratory, the students obtained the following results from a clayey soil. Liquid limit tests: Number of Moisture blows, N content (%) 14 38.4 16 36.5 20 33.1 28 27.0 Plastic limit tests: Students conducted two trials and found that PL= 17.2% for the 1st trial and PL = 17.8% for the second trial. Draw the flow curve and obtain the liquid limit. What is the plasticity index of the soil? (Hint: Use an average value of PL) Determine the flow index. Determine the liquidity index of the soil if the in-situ moisture content is 21%, and comment on the probable engineering behavior of this soil.

A sample of saturated clay was placed in a container and weighed. The weight was 6N. The clay in its container was placed in an oven for 24 hours at 105˚C. The weight reduced to a constant value of 5N. The weight of the container is 1N. If Gs = 2.7, determine: a) Water Content  b) Void Ratio  c) Bulk Unit Weight  d) Dry Unit Weight  e) Effective Unit Weight
