Boundary layer thickness in laminar flow over a flat plate increases as(where, d = distance from the leading edge.) ?
Correct answer: A. √d
- A. √d
- B. d1/3
- C. d2
- D. d2/3
Explanation
For laminar flow over a flat plate, boundary-layer thickness varies approximately as δ ∝ √x, where x is the distance from the leading edge. Thus the layer grows rapidly near the leading edge and progressively more slowly downstream.
