_______________ number indicates the ratio of the rates of the heat and mass transfer incase of a cooling tower?
Correct answer: B. Lewis
- A. Sherwood
- B. Lewis
- C. Stanton
- D. Peclet
Explanation
The Lewis number compares thermal diffusivity with mass diffusivity and therefore relates the rates of heat and mass transfer in cooling-tower analysis. Sherwood measures mass-transfer relative to diffusion, while Stanton is a transfer coefficient group.
