The determination of fluid viscosity using tracker-assisted falling ball viscosimeter

Abstract

This study intends to determine fluid viscosity. The method adopted was the utilization of a tracker-assisted falling ball viscosimeter. The falling ball viscosimeter was employed to get the motion of objects in the fluid, which was then recorded with a video recorder. The motion of objects in the video was analyzed by tracker software to get the terminal speed value of objects in the fluid. The value of fluid viscosity was then calculated using Stokes' law. The results showed that the liquid viscosity value was 1.298 N.s/m2.
