Grade stakes for a pipeline running between stations 0 + 00 and 6 + 37 are to be set at each full station. Elevations of the pipe invert must be 843.95 ft at station0 + 00 and 847.22 ft at 6 + 37, with a uniform grade between. After staking an offset centerline, an instrument is set up nearby, and a plus sight of 5.32 taken on BMA (elevation 853.63 ft). The following minus sights are taken with the rod held on ground at each stake: (0 + 00, 5.36); (1 + 00, 5.86); (2 + 00, 5.88); (3 + 00, 6.47); (4 + 00, 7.53); (5 + 00, 8.42); (6 + 00, 8.89); (6 + 37, 9.12); and (A, 5.36). Prepare a set of suitable field notes for this project (see Plate B.6 in Appendix B) and compute the cut required at each stake. Close the level circuit on the benchmark.
A nozzle discharges a stream of water with an initial velocity v0 of 50 ft/s into the end of a horizontal pipe of inside diameter d=5ft. determine the largest distance x that the stream can reach.
in inclined circular gate with water on one side shown in the figure. determine the total resultant force acting on the gate and the total location of center pressure.
A toothpaste factory situated on a large river disposes of a waste water containing villiamite (NaF) to the river on a continuous basis. The minimum flow in the river is 210 m3/s, and the discharge rate from the treatment plant is 12.5 m3/s.
In water and wastewater treatment process a filtration device may be used to remove water from the sludge formed by the precipitation reaction. The initial concentration of sludge from softening reaction is 2% (20,000 mg/L) and the volume of sludge i..
The area shown is revolved about the x axis to form a homogeneous solid of revolution of mass m. Using direct integration, express the mass moment of inertia of the solid with respect to the x axis in terms of m and h
There are three reactors degrading a chemical biologically, at three degradation rates; i.e., 0.2 d^-1, 0.4 d^-1, and 1.0 d^-1. The residence time of the chemical in these reactors are 10 d, 5 d, and 55 d, respectively.
Assuming a density of 120/ft^3 for masonry brick work, determine the max height of a brick wall if the allowable compressive stress is limited to 150/in^2 and the brick is a) 4" wide b) 6" wide.
Find the volume of the given solid region bounded below by the cone z=sqrt(x^2+y^2) and bounded above by the sphere x^2+y^2+z^2=128. using triple intergrals
Bike comes in many forms, each aimed at a particular sector of the market such as Sprint bikes and Mountain bikes - Use your judgement to identify the primary objective and the constraints that must be met for each of these
A bicyclist is riding a bicycle on a flat road. The combined mass of the bicyclist and bicycle is = 110kg, the radius of each wheel is = 32.5cm, and the coefficient of rolling resistance between the tires and the road is = 0.245 cm.
A floating platform is supported at each corner by a hollow sealed cylinder 1 m in diameter, the platform itself weighs 25kN in air and each cylinder weighs 1.2kN per meter of length.
On the two lane carriageways, roadworks restrict the width of both traffic lanes, generating a bottleneck to the traffic flow. The maximum flow per lane on the unobstructed carriageway is 2100 vehicles per hour whilst on the section under repairing t..
