The ratio of kinematic viscosity to thermal diffusivity is called the _______________ number?
Correct answer: B. Prandtl
- A. Peclet
- B. Prandtl
- C. Stanton
- D. Nusselt
Explanation
The ratio of momentum diffusivity to thermal diffusivity is the Prandtl number, Pr = ν/α. The Peclet number instead compares convective transport with thermal diffusion and equals Re × Pr.
