True one-dimensional flow occurs when________?
Athe direction and magnitude of the veiocity at all points are identical
Bthe fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
Cthe velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
Dthe magnitude and direction of the velocity do not change from point to point in the fluid
Evelocity, depth, pressure etc. change from point to point in the fluid flow
Correct answer
A. the direction and magnitude of the veiocity at all points are identical
Explanation
The correct answer is the direction and magnitude of the veiocity at all points are identical.
