COMPARATIVE STUDIES OF VISCOSITY FROM DIFFERENT LIQUID USING STOKE'S LAW EXPERIMENTAL APPROACH

This study investigates the viscosity of various liquids through a comparative analysis employing Stokes' law and an experimental approach. Viscosity is a fundamental property of fluids, plays a crucial role in diverse fields, including industrial processes, materials science, and biological applications. Stokes' law, which describes the motion of spheres in viscous media, serves as the theoretical framework for this research. In achieving the aim and objects of this research in determining the viscosity from the following liquids: water (H₂O), cooking oil (palm oil), groundnut oil, engine oil, and glycerin, the following materials were used: a clamp and retort stand, fluids (five different fluids), glass tube, funnel, stop watch, meter rule, micro-meter screw gauge, beam balance. The diameter of the ball bearing were measured and recorded for each ball bearing and was recorded for five different ball bearings. The clamp and retort stand was used to hold the glass tube firmly, to avoid the glass tube or cylinder falling down during the practical. The fluids that were used are groundnut oil, palm oil, glycerin, engine oil and water. This fluid was poured into the glass tube and the level of the fluid was marked. M1 & M2.
