Abstract

This study investigates the impact of liquid viscosity on the fall time of objects in viscosity tests. Viscosity, a measure of a fluid's resistance to flow, plays a crucial role in various industrial applications and scientific research. By employing a range of fluids with different viscosities, we systematically analyzed the fall time of a standardized object through these liquids. The experiments were conducted under controlled conditions to ensure accuracy and repeatability. Our findings indicate a direct correlation between increased viscosity and prolonged fall time, consistent with theoretical predictions. This research contributes to a better understanding of fluid dynamics and provides valuable insights for industries where precise viscosity measurements are essential. The SAE 40 oil viscosity value is 0.15 Nm/s² and the SAE 140 viscosity value is 0.18 Nm/s². The speed of the prayer beads in SAE 40 oil is 0.17 m/s, while in SAE 140 oil it is 0.06 m/s. The marble speed in SAE 40 oil is 0.57 m/s, while in SAE 140 oil it is 0.19 m/s
