Using Darcy's Law, calculate the quantity of groundwater (L/day), the seepage velocity (m/s), and the contaminant loading (Kg/day) to the river (assuming no retardation) for the following scenario. Be sure to include both a plane view and cross-sectional sketches of the conditions analyzed.
Groundwater is flowing through an unconfined, uniform, 3-m-thick sand aquifer and discharging to a river. Two wells located 50 m apart and perpendicular to the flow direction are representative of the formation flow and show a difference in water level of 1m. The hydraulic conductivity of the aquifer is 1 x 10-3 cm/s and the average contaminant concentration throughout the aquifer in the subject area is 200 mg/L. The zone of flow and contamination is 100m long as measured parallel to the river.
A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12 feet, and the superelevation is 0.06 and was set assuming maximum fx.
Could all the people in china hold back the water behind the three gorges dam?
A quartzite sample in a compression testing machine is 180mm long and 54mm in diameter. what is the stress under a load of 100kN? if the modulus of elasticity is 102kN/mm2, find the strain develope in the sample.
The reaction between 2-methyl-2-pentanol and HBr to yield 2-methyl-2-pentene is probably: A) an E1-type reaction involving the protonated alcohol as the substrate. B) an SN2-type reaction involving the protonated alcohol as the substrate.
If friction between the cars and the rails is neglected, what were the magnitude and the direction of the velecity of the cars after the collision?
Given the following data for a vertical curve of a road; G1=-2.5%, G2=+5.5% and station of PVI=250+50.At station 252+50, the vertical curve must intersect an existing road at elevation 48.48ft. the elevation on the tangent section at station 256+5..
Discussion on how sustainability and green engineering can be integrated in the four components of materials science and engineering?
Set up a table showing curve elevations at the PVC, at the PVT, and at the half-station points along the curve. Compute the station and elevation of the curve turning point.
A hawk flying at 2 m/s at an altitude of 45 m accidentally drops its prey. The parabolic trajectory of the falling prey is described by the equation below until it hits the ground, where y is its height above the ground and x is its horizontal dis..
Differentiate between construction loan and mortgage loan based on your understanding (using your own words). Define the following terms in your own words: (a) cap rate, (b) economic value of a project, and (c) gap financing.
A 75g , 30cm--long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 12g ball of clay traveling horizontally at 2.5m/s hits and sticks to the very bottom tip of the rod.
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.
