A falling-head permeability test was conducted on a soil that is classified SM. The diameter and length of the test specimen were 10.55 cm and 17.00 cm, respectively. The cross-sectional area of the standpipe was 2.08 cm², and the water temperature was 20°C. It took 38.6 min for the water in the standpipe to drop from a height of 104.0 cm at the beginning of the test to 91.0 cm at the end of the test. Required Determine the soil's coefficient of permeability, in cm/s. Do not use scientific notation. Include 3 digits at the end of leading zeros, e.g., 0.000123 instead of 1.23 x 10-4. Your 0.

Q- Constant head permeability tests were performed on two soil specimens. S1 and S2. The ratio of height of the two specimens (LS1 : LS2) is 1.5, the ratio of the diameter of specimens (DS1: DS2) is 0.5, and the ratio of the constant head (hs1: hS2) applied on the specimens is 2.0. If the discharge from both the specimens is equal, the ratio of the permeability of the soil specimens (ksl: kS2) is.......
A 50 mm diameter and 90 mm-long silty clay sample was subjected to a falling head permeameter test using a setup similar to the one shown in Figure 6.4b, where the inner diameter of the standpipe was 3.0 mm. The head dropped from 870 mm to 450 mm in 5 minutes. What is the permeability of the sample?
