Abstract: Droplet impact is a natural, common but complex phenomena that occurs in everyday life. It plays an important role in many and almost any situation where fluids is involved. The study of droplet impact in fluid mechanics has been ongoing for many years, but the behaviours that droplets exhibit are still being discussed extensively. Many research have been done and papers published, but there are still numerous potential areas of study that can be done. This study observes the impact of droplets of water, and five other liquids characterised by their low surface tension. Several equations and models from previous studies will be reviewed and referenced in attempt to fit the behaviours of these liquids to a scale that may or may not be existing. This paper will also show that using images of droplets captured from the side has its limitations. By using a relatively new method to capture images of droplets from the bottom, comparisons can be made and the differences in images from the two views can be identified. With this method, more accurate results and wider range of study in the field of fluid mechanics may be possible. A subproject dealing with hydrophobic spray makes use of this method to observe wetting areas of a coated surface.
