In the pitot-tube the velocity of flow at a point is reduced to zero....
The stagnation, the point is the point when a moving fluid is brought to rest. The point at which a vertical line through the heeler centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre. The metacentre remains directly above the centre of buoyancy by definition.

Understanding Stagnation Point
In fluid dynamics, the concept of a stagnation point is crucial when analyzing the behavior of fluids in motion.
What is a Stagnation Point?
- A stagnation point is a location in a fluid flow field where the velocity of the fluid is reduced to zero.
- This occurs when the fluid is brought to rest, often due to an obstacle or a specific point in the flow.
Role of the Pitot Tube
- A Pitot tube is an instrument used to measure fluid flow velocity.
- It works by comparing the static pressure and dynamic pressure of the fluid.
- The tube captures fluid at its tip, effectively creating a stagnation point.
Characteristics of Stagnation Points
- At the stagnation point, the kinetic energy of the fluid is converted into pressure energy, resulting in maximum pressure at that point.
- This behavior is governed by Bernoulli's principle, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
Importance in Fluid Mechanics
- Identifying stagnation points helps in understanding flow behavior around objects, such as airfoils or streamlined bodies.
- Engineers and scientists utilize this concept in designing efficient systems in aerodynamics and hydrodynamics.
In summary, the correct answer to the question regarding the point where the velocity of flow is reduced to zero in a Pitot tube is indeed stagnation point, as it signifies a critical aspect of fluid dynamics where fluid velocity ceases, marking a significant transition in energy states.
