Task 1
2-For case the study shown in figure below, explain how the consolidation process could be expected due to the consolidation of the clay layer, and estimate the period over which this will take place.
2-Referring,again,to case the study shown in figure below, explain how the consolidation process could be accelerate so that the construction of the road pavement could be carried out after a 6 month period of the embankment being build, if the maximum permitted settlement after the construction of the road pavement was 25 mm . you explanation mus be supported by appropriate calculation.
Chemical ‘x' is regulated by EPA and the maximum allowable concentration in water is 10g/L. 1000 kg of chemical ‘x' is released in a lake (volume 1,000 m3) where it undergoes degradation as a first order reaction process
Station 0+00 is at BM which has an elevation of 508.97. During the survey, the backsight (BS) to this monument is recorded as 10.92. The level is then turned to sta 1+48, and the foresight (FS) is recorded as 13.14. Next the level is moved to a new p..
Determine the diameter of commercial steel pipe required to convey a minimum of 300 cfs of water at 60 deg F with a head loss of 1.2 ft per 1000 ft of pipe. Assume pipes are available in the following nominal diameters (inches)
How much extra water does a 21.5 ft, 175-lb concrete can one displace compared to an ultra-lightweight 38-lb Kevlar canoe of the same size carrying the same load
When the ambient air is at 70 degrees Fahreneit, 14.7 psia, and contains 21% oxygen by volume, 4.5 lb of air are pumped into a scuba tank, capacity 0.75 ft^3. What volume of ambient air was compressed?
Detennine (1) the required shaker frequency to cause "resonance" and (2) the dynamic magnification ofresponse compared with static response for that level of damping.
A 1047 steel plate is subjected to a tensile stress of 120 MPa. Given its fracture toughness is 45 MPa?m and Y = 1, (a) Determine the critical crack length to assure the plate will not fail under static loading.
The following data are the temperatures (in °F) of effluent at discharge from a sewage treatment facility on consecutive days: 43 47 51 48 52 50 46 49 45 52 46 51 44 49 46 51 59 45 44 50 48 50 49 50
If the evaporation rate from an open water surface is 0.27 inch/day in Tucson Arizona, what should be the surface area of the lagoon? (Note: arsenic does not evaporate but remains in the liquid water)
For the fully developed flow of water in a smooth 0.15-m pipe at a rate of 0:006m3/s, determine the thickness of a. the laminar sublayer; b. the buffer layer; c. the turbulent core
Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day. At a distance of 20 km downstream of the treatment plant, the Pine River has an ultimate CBOD of 10 mg/L.
A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe,
