For the case of flow of air past a wet bulb thermometer (air water vapour system), the approximate value of h2/ky.Cz is around____________________?
Correct answer: C. 1
- A. 0.60
- B. 0.24
- C. 1
- D. 0.72
Explanation
For the air-water vapour system, the heat and mass transfer coefficients are related through the Lewis relation, whose practical value is approximately unity. This is why the ratio hG/(kyCs) is taken as about 1.
