The following results were obtained from a standard compaction test on a soil:
Mass (g) 2010 2092 2114 2100 2055
Water content (%) 12.8 14.5 15.6 16.8 19.2
The value of Gs is 2.67. Plot the dry density–water content curve and give the optimum water content and maximum dry density. Plot also the curves of zero, 5 and 10% air content and give the value of air content at maximum dry density. The volume of the mould is 1000 cm^3.

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.
