A suspended solid particle of density 2200 kg/m3 is moving at 0.25 m/s of horizontal and 0.15 m/s of vertical velocity respectively in a sedimentation tank. If the depth of the tank is 2.0 m what should be the length of tank to trap the particle in the tank?
Consider two alternative water resource projects, A and B. Project A will cost $2,533,000 and will return $1,000,000 at the end of 5 years and $4,000,000 at the end of 10 years.
Hypothetically, upon leaving the filling station, tire pressure for each tire on the 18-wheeler was measured as 105 psi (gauge), and the wheel contact area with the ground was a 6.0 in by 7.0 in rectangle.
A suspended solids analysis is run on a sample. The tare mass of the crucible and filter is 55.3520 g. A sample of 260 mL is then filtered and the residue dried to constant mass at 103 degrees C.
A W18x130 section is used as a column with one end pinned and the other end is fixed against rotation but free to translate. The length is 12 ft. determine the strength of the A992 steel column.
A dam spillway is to be tested using kinematic similitude (Froude scaling) with a 1:20-scale model. The model flow has an average velocity of 0.7 m/s and a flow rate of 0.06 m3/s.
A trough is 5 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x6 from x=?1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required
Raw primary sludge at a solids concentration of 3% is mixed with waste activated sludge at a solids concentration of 6,000 ppm. The flows are 20 and 25 gal/min, respectively.
In incremental launching method of bridge construction, what are the measures adopted to enhance sufficient resistance of the superstructure during the launching process?
A flow of 90 cfs is carried in a rectangular channel 10ft wide at a depth of 1.6 ft. If the channel is made of smooth concrete (n=0.016), find the slope necessary to sustain a uniform flow at this depth.
A welded connection is in equilibrium under the action of thefour forces shown. Knowing that Fa=8kn and Fb= 16kN, determine the magnitudes of the other forces.
emissions from waste oil combustion may be estimated using ap-42 1.11. A small boler is operated from 10/15/2012 through 4/15/2013 and it is used to burn 45 gallons per hour of a blended waste oil having an ash content of 7%
