The effective stress parameters for a fully saturated clay are known to be c′=15 kn/m2 and φ′=29°. in an unconsolidated-undrained triaxial test on a specimen of the same clay the all-round pressure was 250 kn/m2 and the principal stress difference at failure 134 kn/m2. what was the value of pore water pressure in this specimen at 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.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
