Which of the following is directly concerned with Psychrometry ?
Correct answer: A. Lewis relationship
- A. Lewis relationship
- B. Galileo number
- C. Weber number
- D. Dean number
Explanation
The Lewis relationship connects heat and mass transfer in gas-liquid contact and is fundamental to psychrometric calculations. Galileo, Weber, and Dean numbers are fluid-flow or transport correlations rather than psychrometric relationships.
