Explain streamlines and streamline flow. |
|
Answer» Solution :The path of motion of a FLUID particle is called a line of flow. The path TAKEN by a fluid particle under a steady flow is a streamline. Streamline : The curve whose tangent at any point is in the direction of the fluid VELOCITY at that point.  (a)A typical trajectory of a fluid particle. Path of particle is shown in figure (a).It indicatesstreamline .The velocity of particle at a point is in the direction of tangent drawn at that point . the flow for which such streamlines can be defined is called streamline flow. In unsteady flow , flow of line can be defined but not defined streamline. |
