Question 1:
A cylindrical soil sample is connected to two water reservoirs:
a) Determine the pressure, elevation, and total head at a point one meter above the bottom of the sample (point A).
b) Calculate the pore pressure and effective stress at point A if the soil has a saturated unit weight of 18.7kN/m^3. c) Determine the water flow rate though the sample if the soil has a coefficient of permeability of 0.19 cm/s and the radius of the sample is 20 mm.
d) Is it possible for the soil to reach the “quick condition”(zero effective stress) by raising the level of the water in the upper reservoir? Why or why not?.
