WebFeb 24, 2024 · How to Calculate Viscosity. Calculate the Ball's Density. You'll need to first find out how dense your ball is. The equation is this: ρ = m / v (mass = mass / volume). … WebThe viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced …
Plug the information you have obtained into the formula for viscosity: viscosity = [2 (ps-pl)ga2]/9v where ps is the density of the sphere, p l is the density of the liquid, g is acceleration due to gravity (a fixed value of 9.8 m/s 2 ), a is the radius of the sphere, and v is the velocity of the sphere.
