Dynamic Viscosity

Definition: Dynamic viscosity refers to the measure of a fluid's resistance to flow under an applied force or stress. It is also known as absolute viscosity.

Senses:

1. Physics: In physics, dynamic viscosity is expressed in units of pascal-seconds (Pa·s) or poise (P). It quantifies the internal friction within a fluid as it deforms under shear stress.
2. Fluid Mechanics: In fluid mechanics, dynamic viscosity determines the fluid's behavior and its resistance to flow through pipes, channels, or any other conduits. It plays a crucial role in the study of fluid dynamics.

Sample Sentences:

• Understanding the concept of dynamic viscosity is essential for engineers working on fluid flow applications.
• Water has a much lower dynamic viscosity compared to molasses, allowing it to flow more easily.
• The dynamic viscosity of the oil affects the efficiency of the lubrication system in a car.
• By measuring the dynamic viscosity of a liquid, scientists can determine its characteristics and behavior in various applications.
