Question

The following experimental set up is used for the measurement of soil permeabilitv inflow 2m outfloW Homogeneous Isotropic Soil Ref. Elev 1. What is the hydraulic gradient across the soil sample (i.e. between points A and B)? A. 1.0 B. 0.0 C. 2.33 A. None of the above 2. What are the elevation head, pressure head and total head at point A? A. helev-Orn: hpress-4m; htotal-4m B helev Um pressIm, htotalm C. helev-Orn; hpress-11m; htotal-11m B. None of the above 3. Now assume that the height of the inflow container has been adjusted so that hydraulic gradient across the sample is equal to 2. If the coefficient of permeability of the soil is 1.5 x 10' m/sec, then how much water will be collected as outflow in 15 minutes? Select the closest answer A. 850 ml B. 8.50 x 104 ml C. 3.40 liters C. 3.4 x 103 liters
