In a constant head permeability test, a sample of soil 12cm long and 6cm in diameter discharged 1.8 x10^-3m^3 of water in 15 minutes. The head difference in two piezometers A and B located at 1cm and 11cm, respectively, from the bottom of the sample is 2cm A.Determune the hydraulic conductivity of the soil in cm/s Choices: 0.32,0.40,0.35,0.34 B.Calculate the discharge velocity in mm/s Choices: 0.79,0.68,0.71,0.64 C. How long will it take in minutes for the test to collect 3L of water Choices: 22.29,25,26.15,27.69
