An intake conduit from a well field used to pump ground water is being designed for a town with a population of 23,000 people. Six years ago the population was 21,500 people.
a) assuming deometric growth, calculate the population in 50 years
b) the city planners would like to design the conduit such that it will accommodate the city's demands for 50 years. Given an average daily per capita usage of 177 gpcd, determine the design flow for the conduit. (If required, you may assume the maximum daily per capita usage to be twice the average daily per capita usage.)
Determine the axial and hoop stresses at the lower end of the vessel. A standpipe 12 ft in diameter and 50 ft tall is being con- structed for use as a storage tank for water with a specific weight of 62.4 lb/ft3. The wall thickness of the vessel is..
a brass wire of diameter d=1/6 in is stretched between rigid supports with an initial tension T of 37lb. assume the coefficient of thermal expansion is 10.6X10^-6 / F and the modulus of elasticity is 15X10^6 psi.
The maximum flow rate of a standard shower head is about 3.5 gpm and can be reduced to 2.75 gpm by switching to a low-flow shower head that is equipped with flow controllers. Consider a fam- ily of four, with each person taking a 6-minute shower e..
A 0.20 kg stone attached to a 0.8 m long string is rotated in a horizontal plane. The string makes an angle of 25° with the horizontal. Determine the speed of the stone.
A dense sand has an effective friction angle of 43 and c'=0. A dry, 2.8-inch diameter sample is tested in drained triaxial shear with a confining pressure of 2500 psf. What axial load, P (in pounds), will be required to fail the sample?
an insulated tank is evacuated. Air from the atmosphere at 12 psia and 70 degrees farenheight is allowed to flow into the 100 cubic foot tank. What is the final temp and the final mass of air in the tank just after flow ceases.
An increment of vertical stress of150kpa compress the sample to a void ratio of1.43. What is the over consolidation ratio of the soil at the unloaded condition.
Determine the required height h of the roller coaster so that when it is essentially at rest at the crest of the hill it will reach a speed v= 100km/hr when it comes to the bottom.
A smart, anti armour weappon is launched of an aircraft flying at 250 knots (422 FT/s) straight and level at an altitude of 300FT above the ground, the weapon is released from the aircraft with an initial downward velocity of 15FT/s.
A proposed earthen dam will contain 5,000,000 cubic meters of earth. Soil to be taken from a borrow pit will be compacted to a void ratio of 0.78. The void ratio of soil in the borrow pit is 1.12. Estimate the volume of soil (cubic meters) that mu..
