For a falling a head permeability test, the following data were recorded. Length of soil specimen = 500 mm. Area of soil specimen = 16 cm2 Area of stand pipe = 0.97 cm2 Head difference at time t =0 is 760 mm. Head difference at time t = 6min. is 410mm. The test was conducted at a temp. of 20 ֯C. with a unit wt. of water equal to 9.789 kN/m3 and the viscosity of water at 20 ֯C is 1.005 x 10-3 N.8/m2 . Compute the hydraulic conductivity of the soil. Compute the absolute permeability of the soil. What is the head difference at time t = 4 min?
