Effect of diameter on viscosity value with Stoke’s method using Amrita OLabs

The resistance of a fluid to be changed by either pressure or a surface tension of the fluid is called viscosity. A resistance to a fluid flow can be known if the surface is damaged by an object and then connected to the pressure and tension. Stoke's law states that when a spherical object slides down through an infinite column of a fluid having a certain viscosity value, it drags layer upon layer of the fluid in contact with the object. This study aims to find out whether there is an effect of object diameter and tube diameter on the viscosity value, and to find out whether Amrita OLabs can be used to find the required data. This research method is experimental research that will examine directly from the use of Amrita OLabs which will then be presented qualitatively and quantitatively. The comparison data used is in the form of various object diameters and also various tube diameters. The results show that; Amrita OLabs can be used to find viscosity data because Amrita OLabs is designed for the Stoke method and also the diameter of objects and tubes is very influential in finding viscosity values.
