Fig. 136a. air flowing past the ball will be some what as shown in Fig. 13 6b.The velocity at each point in this figure is the resultant of twovelocities, namely, the velocity due to the stream alone (as shownin Fig. 136a), and the velocity due to the whirl alone. In Fig.136& the velocity of… … Fig. 136&. of the air is less in the region b than it is in the region a. There-fore the excess of pressure in the region a pushes the ball from atowards b. Figures 136a and 1366 show a stream of air flowing past a sta-tionary ball. The same effects, however, are produced when the HYDRAULICS.…
