Which of the following is concerned with both heat and mass transfer ?
Correct answer: A. Lewis relationship
- A. Lewis relationship
- B. Nusselt number
- C. Kutateladze number
- D. Froude number
Explanation
The Lewis relationship connects simultaneous heat and mass transfer, especially in gas-liquid contacting, by relating heat-transfer and mass-transfer coefficients through thermal and mass diffusivities. The other dimensionless numbers primarily describe individual transport or flow effects.
