WebMay 24, 2024 · Stokes’ law of friction for laminar flows around spherical bodies states that the drag force is proportional to the viscosity of the fluid, the flow velocity and the radius of the sphere! The relationship between the viscosity of a fluid and the drag caused on a sphere is used, for example, in so-called falling-sphere viscometers, in order to ... http://ecoursesonline.iasri.res.in/mod/page/view.php?id=1018
(DOC) Falling Sphere Viscometer Ely Dawood
WebThe purpose of this experiment was to determine the dynamic viscosity of a given fluid using the falling sphere viscometer method. Theory. A fluids dynamic viscosity is defined as its resistance to an externally applied shear force. This definition implies that a fluid will resist any change in form. Due to this, if a solid object is placed ...
