1. Mohr-Coulomb shear failure criterion (20 points) In a tri-axial test (with load and confining pressure), the sample has the cohesion of 5 kPa, the angle of friction is 36 degree, It is loaded with a loading level of 50 kPa. Now we start to reduce the confining pressure. Question: what is the critical value of the confining pressure has to reach then the sample start to have shear failure

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
