1.A sample of natural glacial till was taken from below the groundwater table. The water content was found to be 52%. Estimate the wet density, dry density, buoyant density, porosity, and void ratio. Clearly state any necessary assumptions.
2.The dry density of a compacted sand is 1.87 Mg/m^3 and the density of the solids is 2.67 Mg/m^3. What is the water content of the material when saturated. Include a phase diagram.
The mass of the compacted soil specimen is 1.91 kg and its water content is 14.5%. Using a specific gravity of solids of 2.66, compute the degree of saturation, density and unit weight of the compacted soil

The point of dicharge is 5 m abovethe floor, and friction losses in the 50 mm pipe from the resevoirto the tower amount to 2.5 J/kg. At what height in the resevoirmust the water level be kept if the pump can deliver only 0.1kW
If the normal stresses in the x and y direction are given byσx and σy, find the normal strains in these two directions.
A lagoon with volume 1,200 m3 has been receiving a steady flow of a conservative waste at a rate of 100 m3/day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10 mg/L.
find the pressure required to fill the container when the height of the fluid is h = 0.75m at both point 1 (intake 1) and 2 (intake 2). Assume the air is at atmospheric pressure until the water level passes intake 2 (at h = 0.5m) and the air follo..
For the grouped data acting as of each of the data point in an interval was actually located at the midppoint of that interval, compute the sample mean,variance and standard deviation and compare with the results above.
