NSc/NPr is called the______________________?
Correct answer: A. Lewis number
- A. Lewis number
- B. Psychrometric ratio
- C. Sherwood number
- D. Stanton number
Explanation
The ratio Sc/Pr equals the Lewis number, since Sc measures momentum diffusivity relative to mass diffusivity and Pr measures momentum diffusivity relative to thermal diffusivity. Thus their ratio compares thermal diffusivity with mass diffusivity.
