17. What is the primary factor responsible for the generation of a vortex flow?
- Viscosity of the fluid
- Pressure difference within the fluid
- Gravity acting on the fluid
- Temperature difference within the fluid
Answer: B) Pressure difference within the fluid.
Explanation:
A pressure difference within the fluid is the main driving force for the creation of a vortex flow. This pressure difference causes the fluid to move in a swirling motion around a central point.
