Reynold's analogy states that_________________?
Correct answer: A. Nst α f
- A. Nst α f
- B. Nst α NRe
- C. NNu α f
- D. NRe α f
Explanation
Reynolds analogy relates momentum and heat transfer, giving the Stanton number as proportional to the friction factor, commonly written Nst = f/2. Therefore Nst is proportional to f.
