For _______________ Prandtl number values, the heat conduction will be negligible in the buffer zone?
Correct answer: C. High
- A. Extremely low
- B. Low
- C. High
- D. No
Explanation
At high Prandtl numbers, momentum diffusivity is much greater than thermal diffusivity, so heat conduction is relatively negligible in the buffer zone compared with momentum transport.
