3.3.1. Levene's Test

The results of the volume leakage were analyzed by F-testing, where the *p*-value = 0.722 > 0.05 for a differential pressure of 10 Pa, indicating no significant difference between the two variables. The *p*-value = 0.718 > 0.05 for a differential pressure of 25 Pa, indicating no significant difference between the two variables.
