Afalling head permeability test was performed on a sample of clean uniform sand. The initial hydraulics head was 900 mm, the final head was 400 mm, 60 sec were required for the water level in the standpipe to fall. The cross-sectional area of the standpipe was 100 mm2. The sample was 40 mm in diameter and had a length of 180 mm. Determine the coefficient of permeability in Darcy's Law.
