Free vortex- Free and Forced Vortex flow with Examples states: When no external torque is required to rotate the fluid mass that type of flow is called free vortex flow.
Examples: Flow of liquid through a hole provided at the bottom of the container.
Hence, the correct option is (A)

Free vortex:
The flow of water in a wash hand basin when it is being emptied through a central opening is an example of a free vortex.
Explanation:
- Free vortex is a type of vortex flow in which the fluid swirls around a central point without any external forces or constraints.
- In the case of a wash hand basin, when the water is being emptied through a central opening, the water rotates around the center as it drains out.
- This rotation creates a vortex pattern where the water flows in a circular motion towards the center before draining out through the opening.
- The shape of the basin and the central drain create the conditions for this free vortex flow to occur.
Importance of understanding free vortex:
- Understanding free vortex flow is important in various engineering applications such as fluid dynamics and drainage systems.
- It helps engineers and designers optimize the design of drainage systems, pumps, and other fluid handling equipment to ensure efficient and effective flow patterns.
- By understanding the principles of free vortex flow, engineers can design systems that minimize energy loss and maximize the flow rate.
In conclusion, the flow of water in a wash hand basin when it is being emptied through a central opening is a classic example of a free vortex, where the fluid swirls around a central point in a circular motion.
