An investigation at a particular site reveald 10 m of clay overlying 2m of sand resting on bedrock.the water table was found to be at the ground surface and the piezometric level for the sand to be 2m above ground level.if the density of the clay is equal to 2.0 Mg/m3 ,calculate the total vertical stress ,pore water pressure and effective vertical stress at a depth of 5 meters below ground level.
Determine the time required for a car to travel 1 km along a road if the car starts from rest, reaches a max speed at some intermediate point, and then stops at the end of the road. the car can accelerate at 1.5 m/s^2 and decelerates at 2 m/s^2
Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
At standard pressure, 14.7 psi absolute, it holds 0.5-slug of water; rho = 1.94 slug/ft^3. For K = 300,000 psi, when it is filled, how many slugs of water must be added to increase the pressure to 10,000 psi
The pipe contains two 6 in steel elbows, two fully open gate valves, a fully open 90o angle valve, and a swing check valve. If the discharge end of the pipe is located 20 ft higher than the entrance, what is the pressure difference between the two..
A distance is measured with an EDM having the instrument /reflector offset constant set to 0mm. The slope distance is reported as 2435.672 m with a zenith angle reading of 90 degrees 34 minutes and 05 seconds.
Compare bar charts and precedence diagrams in terms of the ease with which activities can be added to the schedule.
The investigation results indicated that the clay had a saturated density of 1.6 Mg/m3, an average initial void ratio of 1.8 and the preconsolidation pressure at the mid depth of the clay layer was 20 kPa.
Compacted one cylinder of the soil describes above problem 1 to compare the new results with shown above. The data obtained included a water content of 32.5% and a total density of 121.9 pcf. Comment on these new findings.
What is the probability that a random sample of 20 time intervals between eruptions has a mean longer than 95 minutes?
on a specific westbound section of highway studies show that the speed-density relationship is u= uf [1-(k/kf)^3.5] It is known that the capacity is 4200 veh/h and the jam density is 210 veh/mi.
you have been selected to assist the structural engineer for a bridge replacement project. your task is to design the
Consider the flow of a gas between two parallel plates. If there were an increase in temperature due to heat transfer along the flow direction, the gas density would decrease. Assume the viscosity is unaffected.
