The speeds at which the phase changed from B to C is
judged by
eyes (Fig. 11). In this paper we term this speed as "critical
speed". These are plotted in Fig.
12 as a function of a basal pressure. However data of disks
having small basal pressure were excluded as with the previous
section. The critical speeds range from 2 m/s to 3 m/s and it is
higher for higher basal pressures. |
