Define kinematic viscosity.
Understand the Problem
The question is asking for a definition of kinematic viscosity, which is a measure of a fluid's internal resistance to flow under the influence of gravity. We can expect to explain what it represents in terms of fluid mechanics and its significance in various fields.
Answer
The ratio of dynamic viscosity to fluid density.
Kinematic viscosity is defined as the ratio of the dynamic viscosity of a fluid to its density.
Answer for screen readers
Kinematic viscosity is defined as the ratio of the dynamic viscosity of a fluid to its density.
More Information
Kinematic viscosity is crucial for understanding how fluids behave under gravitational forces, commonly measured with viscometers in controlled environments.
Tips
A common mistake is confusing kinematic viscosity with dynamic viscosity. Remember, dynamic viscosity measures internal resistance, while kinematic viscosity accounts for density as well.
