5. A falling head permeability was performed on a clayey soils. The initial hydraulic head was 900mm and the final head was 400mm and it takes 60 seconds for the water level in the standpipe to fall. The diameter of the standpipe is 10mm and the soil sample has a diameter of 50mm and a length of 180mm. Determine, a) coefficient of permeability in mm/min, b) the discahrge velocity in mm/min, c) seepage velocity in mm/min if n = 0.35.
