b) Direct

Relationship between Shear Stress and Channel Radius

For fully developed laminar flow in a circular tube, the shear stress is inversely related to the channel radius. This relationship is described by the Hagen-Poiseuille equation, where the shear stress decreases as the radius of the tube increases.

Relationship between Shear Stress and Flow Rate

In fully developed laminar flow in a circular tube, the shear stress and flow rate have a direct relationship. According to the Hagen-Poiseuille equation, as the shear stress increases, the flow rate also increases. This understanding is crucial in analyzing the behavior of fluids in confined spaces.

Fluid dynamics can be a fascinating field of study, especially when exploring fully developed laminar flow in circular tubes. The relationships between shear stress, channel radius, and flow rate provide valuable insights into the behavior of fluids in confined spaces.

Relationship between Shear Stress and Channel Radius

The Hagen-Poiseuille equation reveals that the shear stress in fully developed laminar flow is inversely proportional to the cube of the channel radius. This means that as the radius of the tube increases, the shear stress decreases. Understanding this relationship helps researchers and engineers optimize fluid flow in various applications.

Relationship between Shear Stress and Flow Rate

By rearranging the Hagen-Poiseuille equation, we can see that the flow rate is directly proportional to the shear stress. As the shear stress increases, the flow rate also increases. This direct relationship is essential in designing efficient fluid systems and predicting flow behavior in different scenarios.

Exploring the joy of fluid dynamics in fully developed laminar flow unveils the intricate interplay between shear stress, channel radius, and flow rate. These relationships not only deepen our understanding of fluid behavior but also inspire innovative solutions in various industries.
