19. In a forced vortex, how does the velocity of fluid change with increasing radius from the center?
- Velocity increases linearly
- Velocity remains constant
- Velocity decreases linearly
- Velocity increases exponentially
Answer: C) Velocity decreases linearly.
Explanation:
In a forced vortex, the velocity of fluid decreases linearly with increasing radius from the center due to the conservation of mass and angular momentum. This results in a converging flow pattern.
