A water jet is moving in the positive x-direction at 20 ft/s with a ?ow rate Q = 100 ft3/s. The stream hits a stationary splitter plate such that half of the ?ow diverted upward at ? = 45?and the other half is directed downward at ? = 45?, and both streams have a ?nal speed V = 18 ft/s. Disregarding gravitational e?ects, determine the x- and z-components of the force required to hold the splitter plate in place against the water force.
A particle is traveling in a straight line at a constant speed of 22.9 m/s. Suddenly, a constant force of 10.7 N acts on it, bringing it to a stop in a distance of 63.6 m.
It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m. Four pumps are to be used in 0.5-m diameter wells at the four corners of the site.
A horizontal Curve is designed for a two lane mountainous terrain. The following data are known. intersection angle: 40 degrees tangent length: 436.76 ft Station on PI: 2700+10.65 fs=0.12 e=0.08
A barge has the trapeziodal shape and is 22 m long into the paper. If the total weight of barge and cargo is 350 tons, what is the draft H of the barge when floating in sea water
A 1.5 meter deep vertical wall trench is to be cut in a soil whose unit weight is 17.36 kN/cubic meters, angle of internal friction is 25 degrees, and cohesion is 20.6 kN/square meters. Determine the factor of safety of this trench by the Culmann Met..
List the series of steps involved in converting rural land into development. You may refer to an example of local conditions in your reference jurisdiction or you may use a description of such steps that you find from other sources, but do not limit ..
The gate is rectangular with a horizontal width of 2m perpendicular to the paper. For a depth h = 3m of water, calculate the required force exerted by the hydraulic cylinder to keep the gate just closed.
To orient a transit in azimuth when the transit is set up over a point D, a backsight is taken to another point, C, with vernier A set at the azimuth of the line CD and with the telescope in its inverted position
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
at the bottom of a loop in the vertical plane an airplane has a horizontal velocity of 315 mi/h and is speeding up at a rate of of 10ft/s^2. The radius of curvature of the loop is 1mi. The plane is being tracked by radar at O.
An outdoor track is 125m in diameter. A runner increases her speed at a constant rate from 4 to 7 m/s over a distance of 30m. Determine the magnitude of the total acceleration of the runner 2 s after she begins to increase her speed.
A Particle is traveling on a straight line with velocity v=(3t^2-6t) where t is in sec. if s=4 ft when t=0, determine the position of the particle when t=4s. what is the total distance traveled during time interval t=0 to t=4s
