a. A constant head permeability test was performed on a 30 cm2 (cross sectional area) soil sample. The length of the samples was 10 cm, and a 15 cm head difference was applied during testing. If 20 cm3 of water was collected over 2 minutes, calculate the coefficient of permeability of the soil. b. In a falling head permeability test, the head fell from 62 to 35 cm in 4 minutes. The cross sectional area of the sample is 50 cm2 and the length was 9 cm. If the area of the stand pipe was 0.6 cm2 compute the coefficient of permeability of the soil.
