re shown in Figures 10 and 11. Although the initial velocity of the sprays (fig. 10) was very much greater when the straight or 90° grooves were used, the velocity after 0.0025 second was the same for all three-groove angles. Thus the deceleration was more rapid for the spray produced with the… … .00/ 002 003 004 .005 006 Time, seconds Time, seconds Fig. 10.—Effect of groove helix angle on spray tip velocity.
