A laboratory consolidation test was performed on a clayey soil specimen, which was drained on both top and bottom. The time for 50% consolidation was 6.2 minutes, and the specimen's thickness at 50% consolidation was 0.740 in. Two points on the field consolidation line have coordinates (p1, e1) and (p2, e2) of (1000 psf, 1.167) and (2000 psf, 1.108), respectively. Find the coefficient of permeability of the clay for the given loading range.
a) What flow rate (m 3/s) does the filter handle during production? b) What volume of water is needed for backwashing plus rising the filter in each filter cycle?
Will crack widths be affected by the air entrainment?
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
Explain how the desert air can contain much more h 2 o vapor in the air than the pole, and still a lower humidity than the pole? what causes the difference between dry and moist lapse rate?
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).

A proposed earthen dam will contain 5,000,000 cubic meters of earth. Soil to be taken from a borrow pit will be compacted to a void ratio of 0.78. The void ratio of soil in the borrow pit is 1.12. Estimate the volume of soil (cubic meters) that mu..
Assume that there were 1,100,000 vehicles making a 28.5-mi round trip per day, the average vehicle emission rate for VOCs is 1.3 g/VM , and the molecular weight of the VOC emissions from the mobile sources can still be represented by that of metha..
The volume of fill required is 2500 cubic meters. Find the volume of soil that must be excavated from the borrow pit to furnish the required volume of fill. (in cubic meters).
what is the distiniction b/n point and non point sources of water pollution and thier varation with surface and ground water?
The train passes point A with a speed of 30 m/s and begins to decrease its speed at a constant rate of at = - 0.25 m/s2. Determine the magnitude of the acceleration of the train when it reaches point B, where sAB = 412 m.
A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.00 Hz. Ignoring the mass of the spring, what is the mass of the fish?
