A falling-head permeability test is performed on a fine-grained soil. The soil sample has a length of 12 cm and a cross-sectional area of 6 cm2. The water in the standpipe flowing into the soil is 60 cm above the top of the sample at the start of the test. It falls 5 cm in 30 minutes. The standpipe has a cross-section of 2 cm. (a) Make a sketch of the described conditions. (b) What is the coefficient of permeability in centimeters per second? (c) What is the coefficient of permeability in feet per minute?
