The SI unit of viscosity is Nm-2s.
What is viscosity
Viscosity is an important property of fluid foods. It is defined as the internal friction of a liquid or its ability to resist flow. Viscosity is also a characteristic of the texture of food. Viscosity is a measure of a fluids’ propensity to flow. There are two kinds of viscosity. They are kinematic and dynamic.
- Dynamic viscosity is the relationship between shear stress and the shear rate in a fluid.
- Kinematic viscosity is the relationship between viscous and inertial forces in a fluid.
- Engine oil.
- Cough syrup.
- Corn starch solution.
- Castor oil.
- Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils with a higher viscosity.
