A constant head permeability test was performed on a 40 cm² (cross sectional area) soil sample. The length of the sample was 5 cm, and a 20 cm head difference was applied during testing. If 10 cm³ of water was collected over 60 sec, calculate the coefficient of permeability of the soil. (b) In a falling head permeability test, the head fell from 52 to 25 cm, in 3 minutes. The cross-sectional area of the soil sample is 80 cm²,and the length was 8 cm. If the area of the standpipe was 0.5 cm², compute the coefficient of permeability of the soil.
