1.Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in a rectangular street repair area of 2000 ft*48ft*6in. the aggregate in the stockpile contains 3.1 percent moisture. If the required compaction is 95 percent of the target, how many tons of aggregate will be needed?

2.A vertical pipe of 4 ft diameter and 60 ft long has a pressure head of 22.7 ft of water at its upper end. When the flow of water through it is such that the mean velocity is 16 fps, the pipe friction head loss is hf = 2.8 ft. Find the pressure head at the lower end of the pipe when the flow is downward; upward.
