Afalling-head permeability test is performed on a fine-grained soil. The soil sample has a length of 120 mm and a cross-sectional area of 600 mm2. The water in the standpipe flowing into the soil is 0.60 m above the top of the sample at the start of the test. It falls 50 mm in 30 minutes. The standpipe has a cross-sectional area of 200 mm2. (a) Make a sketch of the described conditions. (b) What is the coefficient of permeability in millimeters per second? (c) What is the coefficient of permeability in feet per minute? (d) On the basis of the calculated value for khyd, what is the probable soil type?
3. A soil sample was taken with a cylindrical metal core having a volume of 300cm³. The soil was saturated with water and then drainage water was allowed to drip. Meanwhile, evaporation of water from the soil was prevented. The drained soil sample weighed 500 g before oven drying and 350 g after oven drying. Calculate the following: a. bulk density (p6) b. moisture content by mass(%0m) and by volume (%0v) c. porosity (assume ps = 2.65 g/cm³) d. cm of water per 100 cm depth of soil %3D
