An Ostwald viscometer, also known as a viscosimeter, is a device used to measure fluid viscosity under one type of flow condition. This fluid viscosity represents the fluid’s resistance to flow. It can be thought of as the fluid’s friction, often referred to as internal friction or thickness.

The method of … WebApr 4, 2024 · Viscosity describes the internal resistance to flow of a fluid (internal friction). It is defined by the shear stress τ required to shift two plates moving relative to each other. The higher the relative velocity Δv of the plates and the smaller the distance Δy between the plates, the greater the shear stress.
