A 500-mm-diameter timber pile of Young's modulus
Groundwater is at the surface. Using the application software program APILES (www.wiley.com/college/budhu),
(a) plot the lateral load-pile head deflection assuming free head pile, an earth pressure coefficient of Ks =1, and an adhesion factor of 0.5;
(b) determine the allowable lateral load;
(c) determine the maximum bending moment at the allowable load; and
(d) determine the pile head deflection at the working load. In APILES, select option 1, stiff clay, and input the effective unit weight of the soil when prompted. APILES creates a text fi le named apiles. txt in the folder that contains APILES. You can copy the data to Excel and plot the load-deflection curve.
A 175 Mi^2 watershed has a 4200 acre reservior within its boundary . The annual watershed runoff to the reservior is 13in. A flow of 120 mgd (368 ac-ft/day) is to be drafted from the reservior. The annual rainfall is 38in.
The floating platform shown is supported at each corner by a hollow sealed cylinder 1 m in diameter. The platform itself weights 30kN in air, and each cylinder weighs 1.0 kN per meter of length
The dissolved oxygen of sample water is 1.5 mg/L. At 25 C, the dissolved oxygen of the dilution water is 8.25 mg/L. You are told the BOD5 of the sample is 130 mg/L. You have a target final dissolved oxygen of 3.0 mg/L
In 1800 an undeveloped country had a population of 10 million with birth and death rates of 60 and 52 per thousand per year. The situation continued until 1900, when the death rate instantaneously was reduced to 10
Calculate the change in length of a 30m measuring tape made of steel when its temperature changes by 84 F. The coefficient of thermal expansion for steel is x = 3.1 x 10^-6 per C
The inflow to a small reservoir during a storm may be described by the equations Q=1000(1-e^-kt) where Q= flow in cfs k= runoff rate = 1.0 per hour t = time in hours The outflow through the dam gates is held constant at 800 cfs
The salt water mixes thoroughly with the fresh water and the mixture overflows out of the tank. If the flow rate out of the tank is 60 liters/minute. Assume freshwater is 1000 kg/m^3, and the salty water is 1020 kg/m^3.
Design an algorithm that lists all possible rearrangements of the symbols in a string of five distinct characters. (in pseudocode)
A concentrated moment is applied to the free end. Determine the maximum bending stress on the outside surface of the cylinder and the maximum bending stress on the inside surface of the cylinder.
Material for an earth filll was available from borrow sites at $6.4 per cubic meter and a void ratio of 0.8. In the compacted state the fill measured 100,000m3 at void ratio of 0.7. what will be the total cost of the material in compacted state?
For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
a rapid sand filter has a loading rate of 8.00 mh surface dimensions of 10 m x 8 m an effective filtration rate of 7.70
