If the particles of a fluid attain such velocities that vary from point to point in magnitude and
direction as well as from instant to instant, the flow is said to be-
-
A.
Uniform flow
-
B.
Laminar flow
-
C.
Non-uniform flow
-
D.
Turbulent flow
Correct Answer:
D. Turbulent flow
Explanation:
Turbulent flow occurs when fluid particles move in a chaotic and irregular manner, with velocities that constantly change in both magnitude and direction at any given point. This type of flow is characterized by rapid variations of pressure and velocity in space and time, distinguishing it from the smooth, parallel layers seen in laminar flow. In this state, the motion of the fluid becomes unpredictable and involves the formation of eddies and vortices.
