You are working on a 1-km highway extension project that requires the construction of a 4-m tall soil embankment with a top width of 15-m and 2H:1V slopes. A borrow-pit (i.e., a place where soils are excavated, to then be placed elsewhere for construction projects) has been identified with e = 0.74, emax = 0.9, emin = 0.5. To avoid excessive road deformations, the soil will be compacted to a relative density of DR = 90% when placed in the embankment.
Your boss estimates that extracting 100,000 m^3 of material from the borrow-pit should be enough for this project. Is your boss correct, or is more material than that needed? To decide, answer these questions:
a) What volume of soil, as placed, is required to build the embankment? [Tip: draw the embankment]
b) What is the void ratio of the material when placed in the embankment?
c) What is the relative density of the material in the borrow-pit?
d) When soil is extracted from the borrow-pit and then compacted it the embankment, how do…

- There are 20 cars traveling at constant speeds on a 1 mile long ring track and the cars can pass each other freely. On the track 25% of the cars are traveling at 20 mph, 50% of the cars are traveling 10 mph, and the remaining 25% of the cars are traveling at an unknown speed. It was known that the space mean speed of all the cars on the track is 20 mph. (a) What is the speed that the remaining 25% of cars are traveling at? (b) If an observer standing on the side of the track counted the number and measured the speed of all cars that passed her for one hour, what is the time-mean speed of all the cars the observer counted?

The outlet of the drawn tubing at the drinking water trough discharges to the atmosphere as a water jet. The outlet of the pipe is approximately 12 ft higher than the water surface of reservoir. Expected water temperature is 70ᵒF. Your objective is to select a pump and check its performance for the specified system. Your tasks include: 1. Determine total dynamic head (TDH) operating against the pump for the design flow rate. Neglect minor losses. Note that H-W is not appropriate for this water temperature, and you need to use D-W. 2. Use the TDH and Qdesign to approach a pump vendor. She provides you the attached four pump performance curves for your consideration. 3. Select the appropriate pump based on the fit of the selection point on the pump performance curves. 4. Develop the system curve. 5. Determine the pump operating point and record the system operating conditions…arrow_forward
