Peclet number (Pe) is given by____________________?
Correct answer: A. Pe = Re.Pr
- A. Pe = Re.Pr
- B. Pe = Re/Pr
- C. Pe = Pr/Re
- D. Pe = Nu.Re
Explanation
For heat transfer, the Peclet number compares convective transport with thermal diffusion and is Pe = Re × Pr. Using Re/Pr would not give the thermal Peclet number.
