Problem 7.69
A rectangular flume of planed timber (n=0.012) slopes 0.5 ft per 1000 ft. (i)Compute the discharge if the width is 7 ft and the depth of water is 3.5 ft. (ii) What would be thedischarge if the width were 3.5 ft and depth of water is 7 ft? (iii) Which of the two forms wouldhave greater capacity and which would require less lumber?
Figure shows a tunnel section on the Colorado River Aqueduct. The area of the
water cross section is 191 ft 2 , and the wetted perimeter is 39.1 ft. The flow is 1600 cfs. If
n=0.013 for the concrete lining, find the slope.

- 7.48 An engineer is making an estimate for a home owner. This owner has a small stream (Q= 1.4 cfs, T = 40°F) that is located at an elevation H = 34 ft above the owner's residence. The owner is proposing to dam the stream, diverting the flow through a pipe (penstock). This flow will spin a hydraulic turbine, which in turn will drive a generator to produce electrical power. Estimate the maximum power in kilowatts that can be generated if there is no head loss and both the turbine and generator are 100% efficient. Also, estimate the power if the head loss is 5.5 ft, the turbine is 70% efficient, and the generator is 90% efficient.

- Post-tensioned AASHTO Type II girders are to be used to support a deck with unsupported span equal to 10 meters. Two levels of Grade 250, 10 x 15.2 mm Ø 7-wire strand are used to tension the girders with 5 tendons per level, where the tendons on top stressed before the ones on the bottom. The girder is simply supported at both ends. The anchors are located 100 mm above the neutral axis at the supports while the eccentricity is measured at 400 mm at the midspan. The tendon profile follows a parabolic shape using a rigid metal sheathing. A concrete topping (slab) 130 mm thick is placed above the beam with a total tributary width of 4 meters. Use maximum values for ranges (table values). Assume that the critical section of the beam is at 0.45LDetermine the losses (friction loss, anchorage, elastic shortening, creep, shrinkage, relaxation).
