The figure (below) shows a device for clearing debris using a jet of air discharged from a nozzle.As shown, the jet is striking a cube-shaped object (density 1900 kg/m³) sitting on the floor.Assume that in all cases that (i) the entire jet is deflected by the cube; and (ii) the cube slidesrather than tumbles.Air jetIf the jet diameter is 38 mm and the air velocity is 25 m/s, what is the heaviest cube that could be moved? What are thedimensions of the cube? If needed, assume the coefficient of friction is 0.60.

Answered: The figure (below) shows a device for…

5. A sprinkler rotates around fixed Point C. The nozzle on Arm A has broken off. So, water exits Arm A in the radial direction, relative to the sprinkler at 2 m/s and the radial velocity of the water is increasing at 0.5 m/s². The sprinkler arms are rotating around Point Cat = 6 rad/s, and because the nozzle has broken, it is decelerating with Ö= -1 rad/s². At that moment, what are the radial (vr) and theta (ve) components of velocity of the water exiting the sprinkler at Point A? b.

A siphon tube is useful for removing liquid from a tank. The siphon tube is first filled with liquid, and then one end is inserted into the tank. Liquid then drains out the other end, as the drawing below illustrates. (a) Using reasoning similar to that employed in obtaining Torricelli's theorem, derive an expression for the speed v of the fluid emerging from the tube. This expression should give v in terms of the vertical height y and the acceleration due to gravity g. (Note that this speed does not depend on the depth d of the tube below the surface of the liquid.) A V = (b) At what minimal value of the vertical distance y will the siphon stop working? Y = h (c) Derive an expression for the absolute pressure at the highest point in the siphon (point A) in terms of the atmospheric pressure Po, the fluid density p, g, and the heights h and y. (Note that the fluid speed at point A is the same as the speed of the fluid emerging from the tube, because the cross-sectional area of the tube…
A storm drain has a maximum capacity of 120 L/min. During heavy rains, an influx of 240 L/min approaches the drain.
