Abstract
The bottle pouring phenomenon has been studied due to its complex process and unique industrial value. This study, based on pouring experiments with six different bottles, discovered a strong quadratic relationship between emptying time and the inclination angle. The f indings of Clanet andSerbywererefined, resulting in anequation for emptying time that accounts for variations in inclination angle. The emptying process of the bottle can be divided into two stages: the bubble stage and the flow stage. It was observed that as the inclination angle increases, the ”bubble stage” occupies a longer duration. Combining experiments and CDF, the exponential relationship between the relative maximum flow rate and the relative bottle mouth diameter was obtained by regression method.
