Abstract
This study focused on the charge calculation of water droplets when submerged in non-polar oil, aiming to characterize the influence of detachment precision and detachment times. The existing setup was refined by incorporating an annular system, comprising a water-filled needle and a tubing mechanism driven by a second syringe, enabling varied detachment times. The secondary tube contained either air or the same non-polar oil as the bath. The methodology involved creating water droplets at the tip of a 34G needle and detaching them at specific time intervals (10s) into a silicone oil-filled acrylic cube equipped with electrodes connected to a high voltage power supply (1kV). The droplet motion was recorded and analyzed using Tracker software, allowing for the visualization and plotting of droplet paths. The addition of the annular system provided a good base to study different detaching times of the droplet.
