Dean number is concerned with the____________________?
Correct answer: B. Fluid flow through helical pipes
- A. Fluid-particle interaction
- B. Fluid flow through helical pipes
- C. Power consumption in agitated vessels
- D. Psychrometry
Explanation
The Dean number characterizes the effect of curvature on flow, especially the secondary circulation produced when fluid moves through a coiled or helical pipe. It is not used for agitator power or psychrometric calculations.
