You can measure the viscosity of a liquid by measuring the velocity of a sphere as it falls through the liquid. The velocity of the sphere, combined with the relative densities of the sphere and the liquid, can be used to calculate the viscosity of the liquid.Dec 6, 2020
How do you measure viscosity?
A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.
How do you test the viscosity of a liquid?
How Is Viscosity Measured? Viscosity cups are used to determine a fluid's kinematic viscosity. This relatively simple test involves placing the fluid in a container with a small opening at the bottom. The fluid is allowed to flow through the opening in a precise amount.Mar 26, 2018
How do you explain viscosity to a child?
Viscosity is the property of a liquid that describes how fast or slowly it will flow. You can think of viscosity as how thick a liquid is. A liquid with high viscosity - that is thick, like peanut butter - will flow slowly.
