A Ping-Pong ball weighs 2.6 g and has a diameter of 3.8 cm. It can be supported by an air jet from a vacuum cleaner outlet as in the image. The following graph shows the CD-Re relation for three-dimensional bodies. For sea-level standard air, what is the required jet velocity? 100 10 Stokes's law: 24/Re - 2:1 Disk normal to stream Sphere 0.1 Ellipsoid Airship hull 0.01 0.1 1 10 100 103 104 105 106 107
