Figure 4 The relationship between microbubble size and its
floating rate
The relationship between the particle size and the average rising rate
is shown in Fig.4. As the particle size of the microbubbles increases,
the average rate increases. The relationship between the average rate
and the particle size of a single microbubble is y = 48.056x + 1814.8
(R2=0.73), and the relationship between the average
rate and the particle size of two microbubbles is y=97.123x-1108.8
(R2=0.77). From the correlation coefficient
R2, in the same water flow environment, whether it is
a single microbubble or a combination of two microbubbles, its average
rate is positively correlated with its particle size, and the effect of
microbubble particle size on the average rate is extremely significant.
