5 Experimental Verification of Dynamic Scaling Theories and Discussions

Figure 5.4: Half-power bandwidth ∆fr in Hz of an acoustical resonance at 790 kHz of a cylindrical cavity resonator filled with the mixture methanol-n-hexane versus tempera- ture T in oC. The system exhibits an upper critical temperature.

where R denotes the radius of the capillary, ∆V the volume of the fluid running during ∆t, the duration of measurement. The kinematic viscosity is defined by:

with the length of capillary l, the falling height h and g the gravitation constant. Finally, the so-called effective shear rate results:
