Question: A partially saturated soil from an earth fill has a natural water content of 19% and a bulk unit weight of 19.33 kN/m3. Assuming the specific gravity of soil solids as 2.7, compute the degree of saturation and void ratio.
If subsequently the soil gets saturated, determine the dry density, buoyant unit weight and saturated unit
The scale of a spring balance reading from 0 to 235 N has a length of 13.0 cm. A fish hanging from the bottom of the spring oscillates....
A 250 mm- diameter and 16 m-long timber pile is driven into a sandy soil where ?= 18 kN/m3 and ?' = 34 degree. Estimate the maximum load allowed on the pile with a safety factor of 2.5
A fireboat pump draws seawater (density=1.95 slugs/ft^3) from a 6 inch diamter submergred pipe that reaches 6 feet under the free surface and discharges 120 ft/s through a 2 inch diamter nozzle 10 feet above the free surface
The diameter of the hole is normally distributed with a mean 15 cm and standard deviation 0.025 cm, and the diameter of the piston is normally distributed with mean 14.88 cm and standard deviation 0.015 cm.
A soil, 150mm x 150mm x 20mm high, is subjected to simple shear deformation. The normal force in the Z direction is 1 kN and the shear force is 0.5 kN. The displacements at the top of the soil in the X and Y directions are delta x = 1mm and delta z =..
The particle-size characteristics of a soil are given in this table. Draw the particle-size distribution curve. X-axis is Particle Size and Y-axis is Percent Finer Particle Size (mm): 0.425, 0.033, 0.018, 0.01, 0.0062, 0.0035, 0.0018, 0.001.
An inspector is paid $10/hr and can sort 10 rings/min. Assume that a new method allows her to sort 20 rings/min but costs $500 to implement. Is it worth implementing the new method for a batch of 50,000 rings? At what point does the new method pay of..
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
Compute and tabulate the notes for an equal-tangent vertical curve, at half stations, that passes through the midpoint of the 0.90% grade.
After operating for a period of time, assume that the opening size decreases to 10-mm due to the accumulation of materials (debris) on the screens.
a 12-lb collar is attached to a spring anchored at point C and can slide on a friction-less rod forming a 30 degree angle with the vertical. The spring has constant k and is unstretched when the collar is at A.
Our ESP is collecting 95% of the particles in our exhaust stream. We are under pressure to improve its performance. It has been suggested that if we were to cool the inlet gas from the present 600°F to 250°F
