The Lewis Number (Le) is defined as the ratio of the Schmidt Number (Sc) and the Prandtl Number (Pr).

The Lewis Number is also the ratio of thermal diffusivity and molecular diffusivity.

You are right @Aman.

None of the options are right.

The Ratio between sc/pr is the right answer.

Aman said:   1 decade ago
No option is correct. Lewis number = Sc/Pr.

Lewis no is the ratio of Sc to Pr.
