Define flow at a hydraulic jump (upstream and downstream) in terms of the types of flow and corresponding Froude number. What is the depth of water at each section (upstream and downstream) compared
Given that uniform flow is subcrital and there is a weir in a rectangular channel, how do you determine what the weir height should be to force the flow to be critical. Draw this transition on a spe
Given that uniform flow is subcritcal and there is a constriction in a rectangular channel, how do you determine what the constricted width would be to force the flow to be critical. Draw this trans
For each subcritcal, critcal, and supercritcal flows, comment on the values for the Froude number, the depth of the water channel, and the specific energy. How do these values compare to each other
If this GCL is used as a liner beneath a 55-ft high landfill with a waste unit weight of 45 lb/ft3, what will be the hydraulic conductivity of the GCL at the bottom of the landfill
Footings for a structure are to be built beneath a basement slab on a clay soil at a depth of 20 ft below present ground level. The groundwater table is 15ft below the ground surface. The soil void-
What is the maximum column load in kips that could be placed on a 4-ft square temporary footing on a sand for which the standard resistance is about N=15 and the water table is at the surface A fact
The size of the house is 28ftx40ftx10ft. For simplicity, assume the roof is flat, covered with 1-in plywood plus asbestos shingles and has 3 1/2 in of fiberglass insulation. There is a wood subfloor
A stratified lake could be idealized as two layers: with 7.0 m of fresh water on top and 10.0 m of cold water (specific gravity = 1.02) on the bottom. What are the pressure heads at the interface an
A 600 mm long solid steel shaft is to transmit a torque of 30 N-m, G=90 GPa, diameter 15mm. Determine (a) Maximum shear stress, and (b) Angle of twist (phi) at the end.
The cost of a 100,000 bbl/d ethanol unit is $40,000,000. From historical records, the capacity exponent ratio for CCR is 0.75. Estimate the cost of a similar ethanol unit with a capacity of 135,000
Given the total dissolved solids in a brine is 20,500 ppm, compute the resisitivity at a reservoir depth of 8,000 feet.
On a certain highway a -6% grade meets a +2% grade at station 70 + 00, elevation 550.97 ft. An equal tangent vertical curve, 800 ft. long, is to be installed to connect these two grades.
A sample of 20 yields a mean 32.4. Test the two sided hypothesis that the sample drawn from a population with a mean of 35 for the following cases. (a) if a variance of the population is 33; and (b)
What is the maximum column load in kips that could be placed on a 4-ft square temporary footing on a sand for which the standard resistance is about N=15 and the water table is at the surface? A fac
A circular plate is loaded with a total load of 60 kips distributed uniformly over the surface at a pressure of 100 psi. Calculate the vertical stress at every combination of the following: (a) Dept
Determine the required thickness of the pipe wall if the operational pressure head (pressure head in the pipe under regular flow conditions) is 40 m and if the flow control valve on the downstream e
Maximum dry unit weight was found to be 114lb/ft^3 at a water content of 13.5% in labratory tests. Results of a field unit weight test were dry unit weight=111lb/ft^3 and a water content 11%.
Based on volume of a sphere V=4/3(pi)r^3, create a table of volume vs. radius allowing radius to vary from 2.0 to 10.0 cm in 1 cm increments. Graph the data from the table on log-log paper using rad
On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak-hour factor is 0.90, and all drivers are regular
A compressible 12-ft clay layer beneath a building is overlain by a stratum of sand and gravel and underlain by impermeable bedrock. The total expected primary consolidation settlement of the compre
A compressible clay layer 10.0m thick has an initial void ratio in situ of 1.026. Tests and computations show that the final void ratio of the clay layer after construction of a structure is 0.978.
A laboratory consolidation test was performed on a clayey soil specimen, which was drained on both top and bottom. The time for 50% consolidation was 6.2 minutes, and the specimen's thickness at 50%
