5-16 A small hand sander for home-workshop use (see Fig. 5-43) is arranged to be ventilated by attaching a vacuum-cleaner hose to an opening in the frame of the unit. Sandpaper is attached to an oscillating pad on the bottom of the machine, and an opening between this pad and the frame of the machine serves as the hood. Take this opening to be 1.0 cm above the plane of the surface being sanded. Assume the sander makes 10 strokes/s, that each stroke is 6 mm long, and that it is desired to collect all particles of 100 um diameter or smaller. (a) Estimate the pulvation distance for a particle of 100-um diameter. Assume that the particle will travel in the plane of the sandpaper. (b) Determine the flow rate of ventilation air required. For a velocity of 10 m/s in the Yacuum-cleaner hose, what diameter should the hose be?
