A constant-head permeability test is performed in a laboratory where the soil sample is 25 cm in length and 6 cm2 in cross-section. The height of the water is maintained at 2 ft at the inflow end and 6 in. at the outlet end. The quantity of water flowing through the sample is 200 ml in 2 minutes. (a) Make a sketch of the described conditions. (b) What is the coefficient of permeability? ***Please include all the units and conversions.
A fine sand was tested in situ to give a coefficient of permeability of 3.7 x107 m/s. A sample of the same sand, 400mm high and 100 mm in diameter was then tested in a constant head permeameter. Water percolated through the soil under a head of 600mm for 5 minutes and the discharge water had a volume of 1300mm. Determine whether the in situ testing was reflected by the laboratory results and If the below water retaining structure is 140m in width, based on a coefficient of permeability of 7.8x10°m/s, determine the quantity of water that will flow through the soil and under the structure per day.
