PROBLEM 1 The following data are for a falling-head permeability test: Length of the soil sample = 500 mm Area of the soil sample = 1600 mm2 Area of the standpipe 97 mm2 At time t = 0, head difference = 410 mm At time t = 10 min, head difference = 185 mm %3D %3D If the test was conducted at 20°C at which ywater = 9.789 kN, 1.005x10-3 N * s/m2, %3D Determine the absolute permeability of soil (cm/sec) b. What was the head difference at t = 7 min ? (cm) a.
