Study Notes
Viscometer and Viscosity
- A viscometer is a device used to measure the viscosity of a fluid.
- The Ostwald viscometer method is used to measure the viscosity of a liquid by determining the time it takes for a certain volume of the liquid to flow through a narrow tube.
- The viscosity of a liquid measures its resistance to flow, or its thickness and stickiness.
