Question

Choose the correct option regarding a streamline.

• A. Speed, not velocity, at all points of a streamline is same
• B. Two streamlines can intersect in case of laminar flow
• C. There is no friction between streamlines in case of steady flow
• D. In a given streamline, velocity of a point can vary with time

Answer 1

Answer:

D. In a given streamline, velocity of a point can vary with time

If we consider a streamline in a pipe of varying diameter we can say that speed of different points in that streamline are different.
