Q.

Two dimensional flows occurs when

  • AThe direction and magnitude of the velocity at all points are identical
  • BThe velocity of successive fluid particles, at any point, is the same at successive periods of time
  • CThe magnitude and direction of the velocity do not change from point to point in the fluid
  • DThe fluid particles move in plane or parallel planes and the streamline patterns are identical in each plane
Correct Answer : (D)

The fluid particles move in plane or parallel planes and the streamline patterns are identical in each plane
