1.If the sieve analysis of this soil indicated that 85% of this soil was finer than #200 sieve, what is its classifications following USCS system (use atterberg limit tests and penetrometer results separately and compare the classifications)?
2.A two-dimensional flow field is given by u=2+xy+3t^2, v=2xy^2+t. Find the velocity and acceleration of a particle of fluid at point (2,3) at t=4. Specify units in terms of L and T.
3.Water flows in a river. At 9AM the flow past bridge 1 is 37.2 m^3/s. At the same instant the flow past bridge 2 is 26.9 m^3/s. At what rate is water being stored in the river between the two bridges at this instant? Assume zero seepage and negligible evaporation.
4.Sketch the flow field defined by u=3y, v=2 and derive expressions for the x and y components of acceleration. Find the magnitude of the velocity and acceleration for the point having the coordinates (3,4). Specify units in terms of L and T.
The concrete post (Ec=3.6*10^6 psi and Ac= 5.5*10^-6/degrees F) is reinforced with six steel bars. each of 7/8-in diameter (Es=29*10^6 psi and As=6.5*10-6/ degrees F).
Collars A and B are connected by a 25 in long wire and can slide freely on frictionless rods. If a 60 lb force Q is applied to B. determine tension in wire when (black) x = 9 in and b) corresponding mag of force P required to maintain equilibrium ..
What is the conversion rate for parts per million by volume (ppmv)conversion. How is this converted into atm, Pa, and torr?
An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
We are digging a hole to build a building. Calculate the energy needed to bring the soil to surface level. Remember the sides of the excavation lie at 45 degrees. Else, the whole would be constantly refilling itself.
The background concentration of atmospheric lead is 0.1 ug/m^3. During a typical hot day in Leadville the mixing height is 500m and the average wind speed is 1.9m/s.
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take. Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
A trapezoidal channel has a bed width of 3.5 m and a side slope of 30 degrees from the horizontal. Determine the critical depth and the critical velocity for a flow of 22 cubic meters per second.
A rear-wheel-drive 3000lb drag race car has a 200-inch wheel base and a center of gravity 20 inches above the pavement and 140 inches behind the front axle. The owners wish to achieve an initial acceleration from rest of 15 ft/s on a level paved s..
a closed tank contains two straified non misicble fluid layers and compressed air. the fluid of the tank is saline water (relative density 1.036) with a total depth of 3.5m. the top fluid layer is oil (relative density of 08.2) with a depth of 0.6..
If the actual coefficient of sliding friction on icy pavementis 0.05, theoretically within what range of speeds could a vehiclebe operated without sliding inward or outward for the following problems.
