An in-compressible fluid flows horizontally in the x-y plane with a velocity given by u = 33 (y/h)^1/2 , where y and h are in meters and h is a constant. Determine the average velocity for the portion of the flow between y = 0 and y =h.
If it is known that the value of the stress exponent, n, for this alloy is 8, compute the steady-stare creep rate at 1300 K and a stress level of 90 MPa.
If rod slides along the horizontal slot with a velocity of 44 ft/s , determine the angular velocity of link BC at the instant
a draw the free-body diagrams for the entire assembly or structure and each of its parts. neglect friction and the
The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e = 0.85 and the initial velocity 6 m/s.neglect friction. (Theta=70 degrees)
1. Povide three non-pavement products that use asphalt and by weight, what is the percent that is asphalt 2. Provide three US and two international locations where asphalt or its parent material, crude oil, originate from for use int the US
at one point on the highway, a 720 ft equal-tangent crest vertical curve exists. measurements show that at 3+40 stations from the PVC, the vertical curve offset is 3.5 ft. assess the adequacy of this existing curve in light of the reconstruction d..
A water treatment plant has 6 settling tanks that operate in parallel (the flow gets split into six equal flow streams), and each tank has a volume of 600 m3.
Estimate the critical pressure of a mixture of methane and n-hexane if the critical temperature of the mixture is known to be 200 F. Compare your answer with the critical pressures of pure methane and pure n-hexane.
A disabled automobile is pulled by means of two ropes as shown. The tension in AB is 400 lb and the angle is 20. knowing that the resultant of the resultant of the two forces applied at A is directed along the axis of the automobile, determine by ..
A gas stream with a particulate loading of 20.0g/m^3 is passed through a 70%-efficient cyclone followed by a 95%-efficient ESP. Calculate the overall efficiency of the system.
The flowrate (q) per unit lenght (ft^2/s) over the spillway shown below is a fuction of the upstream heah H, the acceleration due to gravity g, and the spillway height P.
