A falling-head permeability test gives the following information: - Water flows horizontally through the soil sample. - The soil sample length in the direction of flow is 150 mm. - The cross-sectional area of the soil sample is 1,140 mm2. - The cross-sectional area of the standpipe is 200 mm2. - At the beginning of the test the height of water in the supply standpipe is 1 m above the permeameter. - After 1 hour, the height of water in the supply standpipe is 0.95 m above the permeameter. a) Sketch the arrangement of the set up for this type of measurement. b) Calculate the hydraulic conductivity. c) Which is the probable tested soil
