Fanning friction factor is equal to (where, fB = Blasius friction factor) ?
Correct answer: C. fB/4
- A. 4fB
- B. fB/2
- C. fB/4
- D. 2fB
Explanation
The Blasius factor is commonly given as the Darcy or Darcy-Weisbach friction factor, whereas the Fanning factor is one-fourth of it. Hence, f_Fanning = f_B/4.
