A cylindrical sediment core sample with the dimensions: diameter = 10[cm] and length= 30[cm] is placed in a Darcy experimental setup (see figure below) and fully re-saturated. At steady state the following information was recorded: hydraulic heads h₁ = 15.6[cm] and h₂=9.3[cm], flow Q = 2[ml/min]. cross-sectional area, A sand Datum: 0 Please calculate the following and provide answers with three significant figures: a) Hydraulic conductivity (K) in the unit m/day. K = [m/day] b) Intrinsic permeability (k) assuming that the fluid used in the experiment is pure water at 25°C Report result using scientific notation and in the unit of m². k= [m²] c) Average linear pore water velocity (u) in m/s. Assume that the effective porosity (n) is half the total porosity of 0.3. Report the result in the unit m/d [m/d] 9.00

In a falling head permeability test, the following data was obtained: diameter of standpipe = 1.5 cm; diameter of sample = 10.16 cm; height of water level at beginning of test (h1) = 30 cm; length of sample (L) = 20 cm. The soil had a coefficient of permeability (k) equal to 3.4 x 10°cm/sec. If the test was conducted for a period of 8 hours, what was the water level at the end of the test (h2)? %3D Time when water level is at h, is t, (t,) a = area of standpipe Time when level is at 19% h, is t2 (t2) A = cross-sectional area of soil sample Soil sample

In a constant head permeability test in the laboratory as shown in Figure Q2(e), the data is recorded in Table Q2(b). The void ratio of the soil specimen is 0.46. Determine; (i) Hydraulic conductivity, k, of the soil in cm/sec. (ii) Discharge velocity in cm/sec.
