Mathematics · Geotechnical Engineering - Fluid Flow
A sand sample of 35 cm2 cross-sectional area and 20 cm length was tested in a constant head permeameter. Under a hydraulic head of 60 cm, the discharge was 120 ml in 6 min. The dry weight of the sand used for the test was 1120 g, and its specific gravity G = 2.68. Determine the seepage velocity of flow.
