1.You are constructing an embankment of 250,000 cubic yards of material. The material has a shrink percentage of 18%. How many bank cubic yards will be required to complete this embankment?
2.A soil borrow material in its natural state in the ground has a unit weight of 85 pfc. When a sample of this soil is dried in the laboratory, its dry unit weight is 72 pfc. What is the water content of this borrow material.
3.The bottom of a rectangular flume is 5m above reference level. The depth of the water in the flume is 3m. The average velocity is 1.7m/s. Compute the hydraulic energy at the surface of the water and at the bottom of the flume.
If a 100 horsepower pump is used to pump water (rho = 1.94 slugs/ft3) from a lake to a raised reservoir what is the maximum elevation of the reservoir above the lake if the pump operates at 30 cubic feet per second
