Understanding Free Vortex
In fluid dynamics, a free vortex is a flow pattern where the fluid moves in a circular path around a central axis. The characteristics of a free vortex are crucial to understanding its behavior.
Velocity Behavior in a Free Vortex
In a free vortex, the velocity of the fluid particles exhibits a specific trend:
Explanation of the Velocity Trend
The decrease in velocity with radius can be explained through the following points:
Conclusion
Thus, in a free vortex, it is indeed correct that the velocity decreases with radius, making option 'A' the correct answer. Understanding this behavior is essential for various applications in fluid mechanics and related fields.

Velocity Behavior in a Free Vortex
In a free vortex, the velocity of the fluid particles exhibits a specific trend:
- Decreases with Radius: As you move further from the center of the vortex, the velocity decreases. This is a fundamental property of free vortices.
Explanation of the Velocity Trend
The decrease in velocity with radius can be explained through the following points:
- Conservation of Angular Momentum: In a free vortex, angular momentum is conserved. As the radius increases, the same amount of angular momentum is distributed over a larger radius, leading to a decrease in linear velocity.
- Velocity Formula: The relationship can be mathematically expressed as \( V = \frac{C}{r} \), where \( V \) is the velocity, \( C \) is a constant, and \( r \) is the radius from the center. This shows that as \( r \) increases, \( V \) decreases.
- Centrifugal Effects: The outward centrifugal force experienced by fluid particles also contributes to the decrease in velocity as they move outward in the vortex.
Conclusion
Thus, in a free vortex, it is indeed correct that the velocity decreases with radius, making option 'A' the correct answer. Understanding this behavior is essential for various applications in fluid mechanics and related fields.
