Boundary layer thickness in turbulent flow over a flat plate increases as(where, d = distance from the leading edge.) ?
Correct answer: C. d4/5
- A. √d
- B. d2/3
- C. d4/5
- D. d1/3
Explanation
For turbulent flow over a flat plate, the empirical boundary-layer relation gives δ proportional to d^(4/5). The d^(1/2) dependence belongs approximately to laminar flow.
