Transition from laminar flow to turbulent flow is aided by the__________________?
Correct answer: C. All A., B. & C.
- A. Surface roughness and curvature (i.e. sharp corners)
- B. Vibration
- C. All A., B. & C.
- D. Pressure gradient and the compressibility of the flowing medium
Explanation
Disturbances such as roughness, sharp curvature, vibration, and adverse pressure gradients can amplify flow disturbances and promote transition. Therefore, all three listed groups can aid the change from laminar to turbulent flow.
