Question 1: A grain of sand (p 1690 kg/m3) that has a 1.5 mm diameter falls into a saltwater pond that is 12 m deep. The saltwater has a density of ?-1024 kg/m3 and a viscosity of ? = 0.960P. Calculate how much time (in seconds) it will take the sand grain to hit the bottom of the pond. Assume that the grain achieves its terminal velocity almost immediately after being dropped.

When attempting to excavate a deep cutting in soft CLAY a
failure took place when the height of the slope reached 10 m. The
cutting has a slope of 1 vertical to 1.5 horizontal. The strata
consisted of 15 m of soft clay, underlain by hard shale. Assuming
that the bulk unit weight of clay is 20 kN/m3.
