Explanation:
Kinematic Viscosity:
- Kinematic viscosity is a measure of a fluid's resistance to flow under the influence of gravity.
- It is defined as the ratio of dynamic viscosity to density of the fluid.
- The formula for kinematic viscosity is: Kinematic Viscosity = Dynamic Viscosity / Density
Dynamic Viscosity:
- Dynamic viscosity is a measure of a fluid's resistance to shear or flow.
- It represents the internal friction of a moving fluid.
- It is typically denoted by the symbol 'μ'.
Relationship between Kinematic Viscosity, Dynamic Viscosity, and Density:
- Kinematic Viscosity = Dynamic Viscosity / Density
- This relationship shows that kinematic viscosity is directly proportional to dynamic viscosity and inversely proportional to density.
- Therefore, the correct answer to the given question is option 'C', which states Kinematic Viscosity = Dynamic Viscosity / Density.
In conclusion, kinematic viscosity is defined as the ratio of dynamic viscosity to density, and it is an important parameter in fluid mechanics to characterize the flow behavior of fluids. Understanding the relationship between kinematic viscosity, dynamic viscosity, and density is crucial in various engineering applications, including in the design and analysis of fluid flow systems.
