State the difference between-

(1)Streamline and turbulent flow

(2)Adhesive and Cohesive forces

Hi Sayali!

Streamline flow:

The flow of a fluid is said to be streamline (also known as steady flow or laminar flow), if every particle of the fluid follows exactly the path of its preceding particle and has the same velocity as that of its preceding particle when crossing a fixed point of reference.

Turbulent flow:

The flow of a fluid is said to be turbulent or disorderly, if its velocity is greater than its critical velocity. Critical velocity of a fluid is that velocity up to which the fluid flow is streamlined and above which its flow becomes turbulent. When the velocity of a fluid exceeds the critical velocity, the paths and velocities of the fluid particles begin to change continuously and haphazardly. The flow loses all its orderliness and is called turbulent flow.

Cohesion is the intermolecular attraction between like-molecules. Adhesion is any attraction process between dissimilar molecular species.

Cheers!!

  • Stremline A stremline is the fixed path followed by an orderly procession of paticles in thesteady flow of a liquid it may be state or curved.In the latter case the tangent drawn to it at any point gives the direction of flow of the liquid at that point.
