Water under a gage pressure of 65 psi flows with a velocity of 12.5fps through a right-angled bend that has a uniform diameter of10in. The bend lies in a horizontal plane, and water enters fromthe west and leaves toward the north. Assuming no drop in pressure,what is the magnitude and direction of the resultant force actingon the bend?
A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12 feet, and the superelevation is 0.06 and was set assuming maximum fx. If the necessary sight distance required 52 feet of lateral clearance from the roadw..
a cantilever beam is additionally supported using two tierods. Both rods attach to the end of the beam. One rodcomes off at 45 degrees and attaches to the same wall that the beamis solidly fixed to
Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
An embankment for a highway 30m wide & 1.5m in a compacted thickness is to be constructed from a sandy trucked from a borrow pit. the water contenet of the sandy soil in the borrow pit is 15%& its void ratio is 0.69.
Calculate the area of flow, hydraulic radius, wet perimeter, and top width of a 12-inch diameter pipe that flows at 1/4 of its capacity.
A fireboat pump draws seawater (density=1.95 slugs/ft^3) from a 6 inch diamter submergred pipe that reaches 6 feet under the free surface and discharges 120 ft/s through a 2 inch diamter nozzle 10 feet above the free surface.
The concentration of ammonia is 6 mg/L at one point in the river. If the first - order decay coefficient for the conversion of ammonia to nitrate is 0.05 day-1, what will the ammonia concentration be 10 miles downstream.
The sports car has a mass of 2.3 Mg and accelerates. at 6m=s2, starting from rest. If the drag resistance on the car. due to the wind is F D = (10v) N, where v is the velocity in m/s,
An 18-m-long steel wire of 5-mm diameter is to be used in the manufacture of a pretested concrete beam.It is observed that the wire stretches 45 mm when a tensile force P is applied.
Light-Voice Controlling System. We are planning to design a new light-voice controlling system. The voices will basically coordinate the crossing of a road by blind people. Suppose the crossing will be operated by two coordinated systems
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C(dot)t product of 10 (mg/L) (dot)min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
Water at 70oC (row = 1.94 slugs/ft3) flows out of a nozzle (diam. = 1in) with a velocity of 10 ft/s at an individual holding a protective shield. If the water deflects off of the shield perpendicular to the original stream in all directions
