Question

Which of the following is a characteristic of turbulent flow?

• A. velocity more than critical velocity
• B. irregular flow
• C. molecules crossing from one layer to the other
• D. All of the above

Answer 1

The correct option is D All of the above

In turbulent flow, the motion of a particle after it passes a particular point may be quite different from the motion of the particle that preceded it at that point. Turbulent flow is characterized by randomness or irreproducibility of the motion of individual particles. It usually occurs in fluids moving at high speeds, beyond a critical velocity.

Hence all the given options are correct.
