## Stokes method to find viscosity

Absolute, Dynamic and Kinematic Viscosity Saybolt Universal Seconds (or SUS) is an alternative unit for measuring viscosity. The efflux time is Saybolt Universal Seconds (SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer - under a carefully controlled temperature and as prescribed by test method ASTM D 88 Viscosity: Definition, Unit & Formula | Sciencing

Where η is the viscosity of the fluid, r is the radius of the ball and is the terminal velocity of the ball in that particular fluid. Plugging everything into the equation we can then find our expression for Stokes law. Rearranging the equation above we can then find an expression for the viscosity of the fluid. MEASUREMENT OF VISCOSITY OF LIQUID Objectives: … by the dynamic viscosity η. For a sphere of radius r moving at velocity vin an infinitely extended fluid of dynamic viscosity η, G.G. Stokes derived an expression for the frictional force: F 1 6 r v (1) If the sphere falls vertically in the fluid, after a time, it will move at a constant Measurement of Viscosity in a Vertical Falling Ball Viscometer The drag coefficient of a sphere, C d, has been tested and the results plotted against the Reynolds number. 7–9 Assuming the inertia terms in the equation of motion of a viscous fluid can be disregarded in favor of the terms involving the viscosity, Stokes’ law states the drag coefficient as the form, C d = 24/Re. Figure 1 depicts the drag coefficient versus Reynolds number with the Determine viscosity using falling sphere (Stokes Law ...

## (1)Viscosity is the tendency of the fluid to resist motion. Essentially it is a measure of the frictional force between adjacent layers of fluid as they slide past each other. (2) Definition: consider two parallel plates of area A, separated by a fluid layer of thickness d.

To determine the coefficient of viscosity of a given viscous liquid by measuring terminal velocity of a given spherical body. Viscosity of a liquid - Stoke's method. THEORY. Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. Viscosity describes a fluid's internal  20 Sep 2018 To determine the co-efficient of viscosity of the given liquid by stoke's method. Knowing the terminal velocity, the size and density of the sphere, and the density of the liquid, Stokes' law can be used to calculate the viscosity of the fluid. To measure the viscosity of supplied sample liquids. Apparatus: extended fluid of dynamic viscosity η, G.G. Stokes derived an expression for the frictional force  Download Citation | Determining the viscosity of liquids using an extended falling ball method | In this article, I will extend the falling ball method to measure the
