The Navier Stokes equations in the z-direction. Define what each term in the equation means. Overall, what quantity is being conserved? Under what conditions might you be justified in assuming that non-linear terms are not important? Finally, if non-linear terms and viscous stress is not important, what does the equation reduce to in steady flow?
The linkage shown is made up of two 3-kg rectangular members (0.4 m by 0.1 m), and is flying through the air. At the instant shown, the vertical member has angular velocity 4 rad/s, and the angled member has angular velocity 1 rad/s.
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
A tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. What measurements should be laid out to establish a horizontal distance of 682.25ft?
Write the mass balance equation for a plug flow with a second order decaying substance,C. Solve for the steady state concentration of C as a function of the second order rate constant k, longitudinal distance x, mean velocity u, and the concentrat..
Compute the maximum acceptable service load on an A36 steel plate tension member 1/4in.x12in. having a single line of holes parallel to the direction of loading. The load is 25% dead load and 75% live load, and 7/8in. diameter bolts are used.
An aluminum rod (1) (E=80 GPa, d=24.5 x 10-6/oC) and a brass rod (2) (E=115 GPa, d=22.0 x 10-6/oC) are connected to rigid supports. The cross-sectional areas of rod (1) and (2) are 4,000 mm2 and 5,000 mm2
Rigid members ABC and DEF are joined with steel links BE and CF using 25mm pins. The links are made of 25mm thick 50mm wide plates and are single shear. Determine the maximum normal stress in each of links BE and CF
For energy conservation, materials with a high thermal capacity are effective in climates in which the heat flow through the building envelope is:
For each of the following, draw both the p - v and the T - v diagrams showing the location of the state and write below the diagrams a) what the condition the H2O is in (eg. Superheated vapor), b) which table in the back of the text provides the e..
A 100 ft cut steel tape was used to measure between two property markers. The rear surveyor held 93 ft, while the head surveyor cut .67ft. What was the distance between the markers
For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
A clean-earth trapezoidal channel with a bottom width of 1.8 m and a side surface slope 1:1 is to drain water uniformly at a rate of 8 m^3/s to a distance ok 1 km. If the flow depth is not to exceed 1.2 m,
