Figure 3.

(a) Frequency of droplet generation as a function of the inlet gauge pressure for the organic solution (inlet 1) $p_{\mathrm{org}}$ and that for the aqueous solution (inlet 2) $p_{\mathrm{aq}}$. Data points are plotted only in regions where the droplets were generated. (b) Radius of the generated droplet as a function of the inlet pressure for the organic solution (inlet 1) $p_{\mathrm{org}}$ and that for the aqueous solution (inlet 2) $p_{\mathrm{aq}}$.
