Chapter 14, Problem 14.3.1P

A gravity dam has triangular cross section, with the upstream face vertical and impounded water flushed with the crest. The height of the strcuture is 8m while its base is 6 m long. If there is no hydrostatic uplift and friction coefficient between base and the foundation is 0.80. Find the factor against overturning. Specific weight of concrete is 23,540 N/m^3. a. 2.67 b. 1.44 c. 1.90 d. 2.57 With F.B.D

A trapezoidal canal has one side vertical and the other sloping 1:1. The discharge is known to be 20 m³/s at a mean velocity of 1.2 m/s. If the slope is to be minimum as possible, and n=0.015, (a) At what depth is it flowing in m? (b)What is the value of this minimum slope?  Please answer this immediately. Thank you!

Describe about the categories of concrete-masonry dams?

Determine the resultant of the three forces acting on the dam and locate its intersection with the base AB. For good design, this intersection should occur within the middle third of the base. Does it?

A trapezoidal channel having side slope (1:1) it is required to discharge 1.478 m3/sec of water per each square meter of channel area, bed slope (1 to 1000). If this channel is unlined and the value of C=44 and when this channel is lined with concrete the value C=60. The cost per cubic meter of excavation is four times the cost per square meter of lining. The channel is to be the most efficient one find whether the lined channel or the unlined channel will be cheaper what will be the dimensions of the economical channel

An existing levee has a top width of 10ft, a top elevation of 10ft above the base, and 3:1(horizontal:vertical) slopes on both sides. If the levee is to be raised to an elevation of 15ft and must meet new standards requiring a 12ft top width, how much additional land space (in ft2) will be needed for the base of the levee per mile of levee length? Assume side slopes remain 3:1. Show all your work   Note - I will downvote wrong answers oly attempt if you are 100 % sure , else skip and aloow others to do

Describe briefly the design measures that are used to improve dam safety factors against sliding, overturning, and overstress (e.g., reallocating drainage gallery, using grout curtain, pretension, and downstream supporting shoulder).

What flow can be exerted in a 1.2m wide rectangular, cement lined channel (n=0.015)laid on a slope of 4m in 10km, if the water flows 0.6m deep?

A 180 degree horizontal bend narrows from a 14in. diameter upstream to a 10in. diameter downstream. If the bend discharges water into the atmosphere at a rate of 20 cfs, determine(a) thevelocity(ft/s)in14-in-sectionofthepipe, (b) thevelocity(ft/s)in10-in-sectionofthepipe, (c) FP (lb), and(d) FR (lb) required to hold the bend in place.
