What is the relationship between kinematic and dynamic viscosity?
Understand the Problem
The question is asking about the relationship between kinematic viscosity and dynamic viscosity, which are two important concepts in fluid mechanics that describe a fluid's resistance to flow and deformation. Kinematic viscosity is the ratio of dynamic viscosity to fluid density, thus understanding how these two properties interact is crucial in fluid dynamics.
Answer
Dynamic viscosity divided by the fluid's density equals kinematic viscosity.
The dynamic viscosity divided by the density of the fluid gives kinematic viscosity.
Answer for screen readers
The dynamic viscosity divided by the density of the fluid gives kinematic viscosity.
More Information
Dynamic viscosity measures the internal resistance of the fluid to flow, while kinematic viscosity accounts for the fluid's density, making it a measure of the fluid's flow under gravity.
Tips
A common mistake is confusing the roles of density and disregarding that kinematic viscosity is a derived property.
