The value of tend and the fitted a and b parameters used for equation (3.5). The five experiments are named by the location of the oil–water interface Loil. The fitting quality is evaluated by the root mean square (RMS) of the difference between the fitted curve and measured values, normalized by the final tubule length, Lend.
| Loil (µm) | 24 | 65 | 70 | 85 | 140 |
| tend (s) | 18.75 | 9.26 | 9.3 | 3.27 | 0.99 |
| a (µm) | 358 | 361 | 363 | 356 | 335 |
| b (–) | 0.197 | 0.220 | 0.193 | 0.201 | 0.120 |
| RMS/Lend | 0.022 | 0.008 | 0.001 | 0.009 | 0.004 |
