1.A reservoir has a capacity of 2.75 million acre-ft. How many years would this supply a city of 100,000 people if evaporation is neglected? Assume a use rate of 180 gpcd.

2.how does the particle shape affect the use of aggregatein base-course materials? in portland cement concrete? in bituminous concrete (asphalt)?

3.The air above the liquid is under a pressure of 5 psig, and the specific gravity of the liquid in the tank is 0.80. If the rectangular gate is 6 ft wide and if y1 = 1 ft and y2 = 10 ft, what force P is required to hold the gate in place?

4.If 100 acres of farmland were developed for urban housing (four houses per acre), what would be the difference in average annual water requirements after the change over? Assume that the irrigation requirement is 2.5 acre-ft of water for a growing season of six months.
