Two dimensional stream function________________?
Correct answer: B. Is constant along a stream line
- A. Relates velocity and pressure
- B. Is constant along a stream line
- C. Is constant along an equipotential surface
- D. None of these
Explanation
For two-dimensional flow, the stream function has the same value at every point on a streamline, so a streamline is a constant-ψ line. This property also helps ensure continuity of an incompressible flow.
