A sample coarse grained soil is 50mm. In diameter and 150mm long was tested in a constant-head apparatus. The soil sample was prepared at a void ratio of 1.5. The total head was kept constant at 300mm and the amount of water is collected in 4 sec. was 50cm^3. The test temperature was 22°C a.) Compute the temperature correction factor. b.) Compute the corrected coefficient of permeability in cm/sec. c.) Compute the interstitial velocity.
