Chapter 14, Problem 14.15P
The cross section of a braced cut supporting a sheet pile installation in a clay soil is shown in Figure 14.22. Given: H = 12 m, γclay = 17.9 kN/m3, ϕ = 0, c = 75 kN/m2, and the center-to-center spacing of struts in plan view, s = 3 m.
- a. Using Peck’s empirical pressure diagrams, draw the earth-pressure envelope.
- b. Determine the strut loads at levels A, B, and C.

The wind speed is 5 m/s at an anemometer located at 10 m. It is a clear sunny day with the sun nearly overhead (Class B conditions). a. Calculate the ground-level cadmium concentration (in ug/m³) at a distance of 2 km directly downwind? [Refer to tables in the textbook to help with this problem] What is the concentration of cadmium (in µg/m³) inside of a house at the location in part (a) after two hours? Note that the initial concentration of cadmium in the house was zero, there are 0.25 air changes per hour (ach), there is no source of cadmium inside the house, and cadmium is considered a conservative pollutant.arrow_forward

The activated sludge system (aeration tank and secondary clarifier) you design needs to remove 85% of the incoming BODs from the primary effluent, giving a final concentration of 30.0 mg BOD5/L exiting the system. Your design will maintain a concentration of 2500 mg VSS/L and F/M ratio of 0.5 g BOD/g VSS d in the aeration tank. In an effort to keep the waste activated sludge low in water, only about 0.1% of the primary effluent flow (Q) exits the WAS line. The secondary effluent has a flow rate of 9990 m³/d. What volume (in m³) will the aeration tank need to be? Write out all equations and state any assumptions as needed. Primary effluent: Aeration tank V, X, S Secondary clarifier Secondary effluent: Q.
