For what value of Prandtl number, the Col-burn analogy is valid ?
Correct answer: B. 0.6 to 120
- A. 0.06 to 120
- B. 0.6 to 120
- C. 1 to 103
- D. 1 to 50
Explanation
The Colburn analogy is commonly applied for Prandtl numbers from about 0.6 to 120. This range supports relating heat-transfer and mass-transfer or momentum-transfer behavior through the j-factor analogy.
