1.The specifications for a project specify that the in-situ soil must be compacted to 98% of its maximum Modified Proctor Density. What is the range of water contents of the in-situ soil that will meet this criteria?
2.from the following field notes template for a 40 ft wide level roadbed with cut slopes of 3:1 and subgrade elevation of 1239.50 ft. determine the end area
HI = 1254.80
46+00 Lt 8.0/60 7.9/27 5.5/10 4.9/0 6.6/24 7.5/60
3.For the beam and loading shown, 2) draw the shear and bending-moment diagrams, B) determine the maximum absolute values of the shear and bendnig moment.
(a) At what angle did the player have to shoot the cue ball so that the eight ball entered the pocket at C? (b) In what direction did the cue ball move after the collision? (c) What percentage of its kinetic energy did the cue ball impart to the e..
For a design storm specified for an urban area in Tennessee, the depth of rainfall is 2.5 inches (6.35 cm). Initial abstraction in depressions on the pervious and impervious areas was estimated at 0.5 inches (1.27 cm).
A subsurface detention basin is installed beneath a street to help prevent flooding. Water from the rain is chanelled into the basin and begins to infiltrate into the ground when it reaches 1ft.
This weir is to be replaced by an uncontracted horizontal weir that will maintain the same upstream depth. Determine the height of the weir if the discharge coefficient is based on the following equation: C = 1.78 * 0.22(H/p)
The x-component of a velocity field is ax+b.If the flow is steady, two-dimentional and incompressible; generate an expression for velocity component in the y-direction as a function of x and y.
calculate the amplitude F0 of the sinusoidal excitation force that is necessary to produce a steady-state vibration with a velocity amplitude of 10 m/s at resonance. what is the corresponding amplitude of the acceleration
A sprinkler system uses an outdoor reservoir at El 50. A fire pump moves Q = 3 ft^3/sec through a 1.0' dia pipe 300' long to an 8" dia main at El 200. To distribute water to sprinklers, a pressure head at the pipe junction hp =100' is required.
The wet mass of a sample of saturated soil is 520 grams. The dry mass, after oven-drying, is 400 grams. Determine the a) water content b)void ration c)saturated unit weight, and d)effective unit weight
QZY, Inc. is evaluating new widget machinesoffered by three companies. The machines have the following characteristics: A B C First cost $15,000 $25,000 $20,000 Maintenance and operating 1,600 400 900
FeCl3 is added to remove excess phosphate. The following reactions occur (the charges are in parentheses): FeCl3 -> Fe(3+) + 3Cl(-) Fe(3+) + PO4(3-) -> FePO4 The equilibrium constant for the second reaction is 10^26.4.
One blend that is gaining popularity is E85, which is 85% ethanol and 15% gasoline. E85 is 80% cleaner burning than gasoline alone, and it reduces our dependency on foreign oil. But a flex-fueled car costs $1,000 more than a conventional gasoline-..
A Kennedy half dollar has a mass of 1.150 X 10-2 Kg. The coins is a mixture of silver and cooper, and in water weights 0.1011 N. What is the mass of the silver
