For flow past a flat plate, if „x‟ is the distance along the plate in the direction of flow, the boundary layer thickness is proportional to________________?
Correct answer: A. √x
- A. √x
- B. 1/√x
- C. x
- D. 1/x
Explanation
For laminar flow over a flat plate, boundary-layer thickness varies as δ ∝ √x because the layer grows downstream by momentum diffusion. The commonly quoted result assumes a laminar boundary layer.
