A truck spils 1 gallon of benzene into an aquifer with an area= 50ft^2 Benzene has a solubility of 1750 ppm, and a specific gravity of 0.873. The aquifer ahs a porosity of 0.25, a hydraulic gradient of 0.004 and a hydraulic conductivity of 1000 gpd/ft2.
a. what is the discharge through the aquifer in gpd?
b. How long will it take the water in the aquifer to travel 100 ft?
c. How long will it take to remove 99% of the benzene from the aquifer? Assume that the volume of aquifer affected is 500 ft^2
A room has a floor area of 500 m^2 and a height of 4 m. THe room is involved in a fire with a constant energy release rate of 1 MW. calculate the time till the smoke layer is 1.5 m from the floor for (a) the case where the leakage areas are at the ..
A rigid rectangular shelf is suspended from a rigid ceiling by mean of four rods of diameter .505 inches. The two rods to the left L1 and L2, are made of steel. The two rods to the right R1 and R2 are made of aluminum.
The engineer in charge of this project investigated severla alternatives to cool the exhaust gas and has concluded that the two most practical solutions would be either the installation of a waste heat boiler or the installation of a spray injecti..
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
Determine the gravitational force acting between two spheres that are touching each other. The mass of each sphere is 400 kg and the radius is 300mm.
a vertical curve with grade1= 3.6% meets the exit grade of -4.7% at PVI located at station 26.50. A vertical curve of 700 feet is propsed to provide the transition between the two grades.
Compute the motor size required to pump 28.3 cms through a 3,050 m long, 3.66 m diameter pipeline to an upper reservoir 610 m above the lower reservoir. Use a friction facter of 0.02 and a pump efficiency of 80 percent.
Some organisms live in shallow ponds, where much of the water will evaporate during the warm, sunny, summer months. How will the concentration of solute change in the water druing this time
Determine the inclination θ of the ladder if the coefficient of static friction between the friction pad A and the ground is μs= 0.3. Assume the wall at B is smooth. The center of gravity for the man is at G.
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..
TCE from a spill accumulates in a depression of a parking lot. Estimate how fast the solvent volatilizes (in g of TCE per cm^2 per unit time) when these conditions exist: a. The wind speed is 2 m/sec and temperature is 20 degrees Celcius.
Dust is removed from the airstream of a municipal incinerator by four dust collectors operating in parallel, each handling 1/4 of the total airflow of 200 m3/min. The airstream contains 10 g/m3 of suspended solids.
