Physics Question on mechanical properties of fluid
Which of the following is a characteristic of turbulent flow?
A
velocity more than critical velocity
B
irregular flow
C
molecules crossi ng from one layer to the other
D
all of the above
Answer
all of the above
Explanation
Solution
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.
