otion; p is the density of the fluid and K the new coefficient which is apparently greatest for a circular or elliptic disk. In the Case of a spheroid moving in the direction of its axis of S3Tnmetry the way in which Tc and ^Tvary with the fineness ratio is shown in Figure 1. In Figure 2 the… … the narrow waist, while the sudden drop in value indicates the effect of a lack of fore and aft symmetry. The curves for Zhave an advantage over those for X: in indicating more clearly the effect of a change in shape. The effect of a flattening of the nose of the hull has been studied by…
