A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm long, is tested in a Constant Head Permeability Apparatus. A constant head of 75 cm is maintained during the test. After 1 min of testing, a total of 945.7 g of water was collected. The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
Devise a appropriate management system that you as a commercial manager for the contractor would recommend to the project team for use on a construction or building contract.
There are many parallels between the industrialization of the United States after Reconstruction and the modernization of the American workforce in the last twenty to thirty (20-30) years as it transitions from industry to a service-oriented econo..
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
The aluminium wire has a radius of 1.1mm. What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
Two immiscible fluids are in contact. Fluid I is denser and is also well mixed. The concentration of species a is cao everywhere within this fluid and the temperature in fluid I is held constant at To.
