A 1000 ft long steel pipe carries water from areservoir with a water elevation at 826ft. The pipe has a diameterof 12in. with a wall thickness of 0.5in. A gate valve at thedownstream end is slowly closed during a half a minute period.Determine the maximum water hammer pressure if the initial pressureat the valve was measured to be 742ft above datum. The elevation ofthe valve is 545ft. Will rate lifesaver.
After compaction the void ratio is reduced to 0.60. Determine: (a) Dry and moist unit weights before and after compaction (b) Degree of saturation after compaction.
If the densities of metals A and B are 4.27 and 6.35 g/cm3, respectively, whereas their respective atomic weights are 61.4 and 125.7 g/mol, determine whether the crystal structure for this alloy is simple cubic
a railway wagon weighing 40 kn and moving with a speed of 8 kmh is stopped by a buffer of 4 springs whose allowable
The storativity of the Jordan Aquifer (a regional confined aquifer) is 5 x 10-4 and the porosity is 0.3. The thickness of the aquifer is 200 ft. The Jordan has been pumped for several decades, yet remains fully saturated.
shaped nozzle such that the velocity along the center line of the flow increased from 1.5 m / s to 15 m / s at a distance of 37.5 m. specify the amount of convective acceleration at the beginning and end of the range.
Helium(15 degrees celsius, 1atm) will be transported in a straight horizontal copper tube over a distance of 150 m at a rate of 0.1 m^3/s. If the pressure drop in the tube should exceed 6 in h20, what is the minimum pipe diameter
A pipeline 1200 ft long and 8 in. in diameter has at its inlet point 75ft of available hydraulic energy with respect to the reference level. The velocity in the pipe is 5 fps: the pressure at its end is 12psi.
determine the maximum horizontal distance that a projectile will have at a height of 60 m above the orgin if it is fired at an angle at 70 degrees from the horizontal with a velocity of 50 m/s
find a chlorine demand occurring in your drinking water distribution system (series of pipes that carry drinking water throughout a city), yet there is no increased chlorine demand in the water going through the treatment plant
A street car line on the center of an 80 ft street makes a 75degrees 24' turn into another street of equal width. Thecorner curb line has R=12 ft. What's the largest R that canbe given a circular curve for the tract center line if the law requires it..
