Question
Distinguish between streamlined flow and turbulent flow.
Advertisements
Solution
| Streamlined flow | Turbulent Flow | |
| 1. | When a liquid flows such that each particle of the liquid passing a point moves along the same path and has the same velocity as its predecessor then flow is said to be streamlined flow. | When the speed of the moving liquid exceeds the critical speed vc, the motion becomes turbulent. |
| 2. | In a streamline flow, the velocity of a fluid at a given point is always constant. | In a turbulent flow, the velocity of a fluid at any point does not remain constant. |
| 3. | The path taken by the particle in this flow is a curve. | The path taken by the particle in this flow becomes erratic and whirlpool. Like circles. |
| 4. | Streamlines do not change and never intersect. | Streamlines and flow tubes change continuously. |
