A subsurface detention basin is installed beneath a street to help prevent flooding. Water from the rain is chanelled into the basin and begins to infiltrate into the ground when it reaches 1ft. The water table sits 29ft beneath the bottom of the basin and the soil in that distance consists of urban fill. The hydrauic conductivity of the soil is 139ft/day and the dimensions of the tank is 78ft by 13ft. What is the infiltration rate? How long will it take to empty the tank?
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
Each exerts a force of 600 N directed at a t= 20.0° anglerelative to the forward motion of the boat. If the boat moves withconstant velocity, find the resistive force exerted by the water on the boat.
A projectile is fired with an initial velocity of 800 ft/s at a target B located 2000 feet above the gun A and at a horizontal distance of 12,000 feet. Neglecting air resistance, determine the value of the angle at which the projectile is fired.
A POTW facility that operates an anaerobic digestion process generates 2200 tones of waste water sludge per year. The solids content of the raw sludge is 4% by weight.
if you had a choice of three kinds of aggregate--a sandstone,a crushed basalt,and a quartizite,you may select the basalt.Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your c..
Determine the required pumping rate. the aquifer has T= 1600 m 2 /day and the wells each have radius of influence of 600m.
When working with flow through pipes , engineers typically have to determine if the flow is laminar or turbulent. Compute the Reynolds number for each of the cases below and determine if the flow is laminar or turbulent. Assume all of the conduits..
If the free surface at a distance from the axis of the vortex, which is sufficient for its effect to be negligible, is 180 mm above datum, what will be the height above datum of a point B on the free surface at a radius of 100 mm
The subway train shown is traveling at a speed of 30 mi/hr in the west direction when the brakes are fully applied on the wheels of cars B and C, causing them to slide on the track, but are not applied on the wheels of car A.
Calculate the uniform flow rate in an earth-lined (n = 0.020) trapezoidal canal having bottom width 3 m, sides sloping 1V : 2H, laid on a slope of 0.0001, and having depth of 1.8 m.
A 1.5m diameter barrel (concrete barrel, well-rounded entrance) that is 20 m long is installed on a slope of 2 percent. The design discharge is 9.5 m^3/s and the inlet will be submerged but not the outlet.
An undisturbed soil sample has a total unit weight of 19.4 kN/m3, a dry unit weight of 16.9 kN/m3, and a specific gravity of soil solids (Gs) of 2.69. If the sample could be saturated without changing its porosity, calculate the amount of water (i..
