an open rectangular tank is 3 meter wide and 4meter long. the tank contains water to depth of 2m and oil (sg=.8) on top of the water to a depth of 1m detrermine the magnitude and location of the resultant fluild force acting on one end of the tank?
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
A 5000 lb truck is being used to lift a 1000 lb boulder B that is on a 200lb pallet A. Knowing the acceleration of the truck is 1ft/s^2, determine a) the horizontal force between the tires and the ground, b) the force between the boulder and the p..
The force exerted on the hand causes torsion of the humerus. Let us assume the cross-section of this wrestler's humerus is approximated as hollow (the marrow has little structural strength) with an outer diameter of 19.0 mm and an inner diameter o..
0.5 m-diameter concrete pipe (5.0 cm rigid wall thickness with rigid pipe walls) carries water 600m before discharging into another reservoir. The surface elevation of the downstream reservoir is 55 m lower than the supply reservoir.
The total phosphate concentration (TOTPO4) in a river is 3.2 mg/L as P. The pH of the river is 7.8. What are the concentrations of H2PO4- and HPO42-
the hull of a boat has a volme of 150m and the total mass of the boat when empty is 8560kg. determine how much load this boat can carry without sinking in a lake.
What additional data and information should he gather,and how should he go about gathering the data information ?
A coal with 6% ash and a heating value of 13,000 Btu/lb is burned in a new power plant. Assume that 30% of the ask falls out as bottom ash in the furnace. Calculate the efficiency of ESP required to meet federal new source performance standards.
the three forces of magnitude P can be replaced by a single, equivalent force R acting at point A. Determine the distance x and the magnitude and direction of R
Plot the ground level concentration of sulfur dioxide as a function of distance from the stack and determine the maximum ground level concentration at both with and without air pollution control and the distance from the stack where the maximum co..
One accident mitigation procedure is called emergency material transfer, in which the material is transported away from the accident site before it becomes involved. We plan on mitigating a crude oil tank fire scenario by pumping the tank empty in..
The vertical velocity of the box at the time that it hits the surface is v= 5m/s. After impact the camera experiences an acceleration of a = -kx, where k is a constant and x is the compression of the packing material.
