The mass diffusivity, the thermal diffusivity and the eddy momentum diffusivity are same for, NPr = NSc = _________________?
Correct answer: A. 1
- A. 1
- B. 0.5
- C. 10
- D. 0
Explanation
Equal mass, thermal, and momentum diffusivities mean that mass diffusivity, thermal diffusivity, and eddy momentum diffusivity have equal ratios, giving Prandtl and Schmidt numbers of unity. Thus, NPr = NSc = 1.
