In a constant-head permeability test a sample of soil12 cm long and 6 cm in diameter discharged at 1.5*10^-3 of water in 10 minutes. The head difference in two piezometers A and B located at 1 cm and 11 cm, respectively, from the bottom of the sample is 2 cm. Determine the hydraulic conductivity of the soil. What is the soil type tested?
