ABSTRACT
Thus, membranes with exactly the same hole with different surface energies were prepared one at a time.
The bubble volume was calculated from the total volume of air passed through a hole and the number of bubbles, which was obtained by playing the recorded videotape, in a given time. The bubble diameters, surface-to-volume ratio, and so forth are derived from the calculated bubble volume, assuming the spherical bubble, although bubbles in water are far from a sphere as seen in figures presented in Chapter 27.
