The dam presented below is 180 m long (in the direction perpendicular to the plane of the
cross-section). For the water elevations given on the drawing:
a) Construct the flow net (minimum number of equipotential lines should be 10),
b) Calculate the rate of seepage for the entire dam,
c) Find the total uplift force on the dam (ignore barriers), and
d) Estimate the hydraulic gradient at points A, B, and D.
Recommended to use a spreadsheet to include all equations for calculations of potentials.
Using A36 steel select the lightest equal leg single angle member to resist a factored (LRFD) tensile load Pu = 167 kips. The member will be connected through one leg with one line of three 3/4-in Ø bolts spaced at 3 in between centers as shown. The edge distances Leh = Lev = 1.5 in. Use LRFD Method Use U from Table D3.1, Case 8. See attached (D3.1 Case 8, Shear Strength of Bolts, Table 1-7 Dimensions of Angles).
The system in Fig. consists of 1200 m of 5 cm cast-iron pipe e=0.26mm, two 45° and four
90° elbows, a globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m,

Some of these vehicles have electronic identifiers that allow them to enter the park immediately, beginning at 8:00 A.M., without stopping (they are billed remotely). All vehicles without such identifiers stop at a single processing booth, but they wait in line until it opens at 8:10 A.M. Once open, the operator processes vehicles at μ(t) = 8 + 0.5t [where μ(t) is in vehicles per minute and t is in minutes after 8:10 A.M.]. An observer notes that at 8:25 there are exactly 20 vehicles in the queue. What percent of arriving vehicles have electronic identifiers and what is the total delay (from the 8:00 A.M. until the queue clears) for those vehicles without the electronic identifiers (assume D/D/1 queuing)?arrow_forward
