The setting velocity of a particle is 0.002 m/s and the overflow rate of a settling tank is 0.008 m/s.
(a) what percent of the particles does the settling tank capture?
(b) If the particles are flocculated so that thie rsettling rate is 0.05 m/s, what fraction of the particles is captured?
(c) If the particles are not charged, and another settling tank is constructed to run in parallel with the original settling tank, will all of the particles be captured?
What are minerals? Sketch different types of mineral crystal forms and list different types of rock forming minerals. Describe with examples the importance of mineral identification in engineering applications.
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..
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.
The soil properties of the clay are Cc = 0.25, Cr = 0.05, gsat = 18 kN/m 3 , for the sand gsat = 18 kN/m 3 , and the water table is 2 m below the soil surface. Determine the settlements when a stress of 100 kPa is applied by the building over an a..
Calculate the fraction of total atrazine that will be adsorbed to the soil given that the soil has an organic carbon content of 2.5%. The bulk density of the soil is 1.25 g/cm3; this means that each cubic centimeter of soil (soil plus water) conta..
For a metal and wood structure, how would the economies of construction be obtained (pertaining to the mean and standard deviation of a probability of failure graph)?
a 110 cubic centimeter volume of clay weighs 145 g in its undisturbed state. when the clay specimen is dried it weighs 110.5g. what is the natural water content of the clay, and what is the degree of saturation Assume Gs=2.70
a spherical balloon is being inflated so that its volume is increasing at the rate of 5 cu meter/min. at what rate is the diameter increasing when the diameter is 12m?
Knowing that the coefficient of kinetic friction between a sled and the run is 0.10 and that the speed of the sled is 25 ft/s at B, determine the tangential component of the acceleration of the sled a) just before it reaches B, b) just after it pa..
An Electrostatic Precipitator must treat 500,000 acfm with 99% efficiency. Assuming an effective drift velocity of 0.4 ft/sec, calculate the required plate area in ft^2, and the number of plates if each is 20 ft tall by 10 ft long, and there are 4..
Determine the velocity and acceleration of block B and determine the velocity and acceleration of Car A relative to Car B.
