Problem 3: A constant-head permeability test was performed on the soil sample shown below. The hydraulic conductivities were 0.04 cm/s for the sand and 0.0004 cm/s for the silt. The cross-sectional area of the sample is 10 cm², of which 9 cm' is sand and the remainder is silt. (a) Plot how the total hydraulic head (expressed in terms of AH) and hydraulic gradient vary along the length of the sample. (b) What would be the hydraulic conductivity (k) for...

answer ir quickly please thanks Question 5 Not yet answered Marked out of 1.00 P Flag question In lecture 3, we calculated the equivalent vertical hydraulic conductivity (KV) of the system below. To three decimal places, Kv 0.0541 m/d. Use this Kv value and the extra information in the diagram below to calculate the Darcy flux (q). Present your answer to three decimal places, with downwards flow being positive. Note, it is best to answer this question after lecture 5....
The figure below shows the soil profile conditions below a 5-m deep pond. Water is seeping directly downward under steady-state conditions through the clay layer into underlying gravel. Assume the elevation datum at the top of the gravel layer and that the hydrostatic ground water table is also found in the top of the gravel and its position does not change with time or amount of flow. For these flow conditions, calculate the following: a. b. c. d. e. f....
*need the uplift force Problem 5 Consider the flow net shown below. The sandy soil has an average saturated unit weight of 20 kN/m and permeability of 0.002 cm/s. Numbers provided are elevations from the interface with the impervious layer. The other "set" of numbers counts the number of head drops. (a) Compute the distribution of pore water pressure acting along the base of the concrete weir, and determine the vertical uplift force that the water pressure exerts on the...
(4). (8 pts). A soil profile is shown in below Figure. A uniformly distributed load Ao is applied at the surface of soil. Given the preconsolidation pressure is between swell index and compression index is: C C/6. The unit weight of water is: -9.38 kN/m. If U-98% we regard it as a completion of primary consolidation. We have taken the clay sample and done the Atterberg Limit test. For the liquid limit test, the result is as below. Please ơ'-926...
