A soil sample is prepared in a hollow cylindrical mould of diameter 46 mm and height 100 mm having a weight of 245 gm. The soil mixture was prepared by mixing 42 gm of water with 300 gm of dry soil mass and was compacted in 5 layers in the cylindrical mould. The specific gravity of the soil solids was found out to be 2.65. The soil mixture filled up to the brim after compaction. Afterwards, a high pressure was applied to compact the sample from both sides.
A decrease in height of 10 mm for the sample from one side was observed.What is the void ratio of the sample before high pressure application?What is the degree of saturation for the sample before high pressure application?Given that after high pressure application, the weight of soil with mould is 560 gm.
What is the void ratio of the sample after high pressure application?What is the degree of saturation of the sample after high pressure application?If the void ratios before and after high pressure application correspond to the void ratio in densest and loosest state, then what is the relative density of the sample, given that the in situ relative compaction is 95% corresponding to the compaction after high pressure application ?
A 30mm pipe X 460 mm rectangular duct carries air. What size square conduit is needed to transport 4m cube per sec of water at a distance of 45m and head loss of of 1.08m.
At a confining pressure of 2000 psi, the first sample failed at 9000 psi. Then at a confining pressure of 5000 psi, the other sample failed at 21,000 psi. Plot the two test results on a shear stress-normal stress diagram and draw in Mohr envelope.
A constant-head permeability test was conducted on a sample of fine silica sand. The cross-sectional area of the sample was 60 cm2 and its length was 150 mm.
Two converging tangents have azimuths of 300 deg and 270 deg respectively, while thAt of the common tangent is 320 deg. The distance from the point of intersection of the tangents to the PI of the second curve is 100m while the stationing of the PI o..

A collar of weight m slideswithout friction on a horizontal rod between springs A and B. Thecollar is pushed to the left, compressing spring A 0.1 m. k of A is1.6 kN/m and k of B is 2.8 kN/m.
a power plant burns 150,000 tonnes (1 tonne = 1,000 kg) of coal each year. The coal has 2.5% sulfur content, and the air pollution control equipment removals approximately 94% of sulfur. Assume 10% of the sulfur content ends up in the ash.
Divide the resulting time histories into 10 equal segments and identify the median peak value for each area and for each wind direction. Identify the locations of the worst--case values and wind directions.
Battered piles are used on many construction projects as a permanent part of the element being constructed. Does this construction method have any play in the construction of a temporary earth retention system?
