A normal shock wave is analogous to
- Aan elementary wave in still liquid
- Bthe hydraulic jumpCorrect
- Csubcritical flow in open channel
- Dflow of liquid through an expanding nozzle.
Solution
Concept
Shock and jump
Step-by-step solution
1. A normal shock in gases is analogous to a hydraulic jump.
Explanation
Both are abrupt transitions with energy loss.
Why the other options are wrong
Others do not behave so.
Shortcut
Shock ↔ jump.
Correct answer: B) the hydraulic jump
