Bernoulli's Equation
GATE 2012
Medium
For uniform laminar flow (in the x-direction) past a flat plate at high Reynolds number, the local boundary layer thickness (δ) varies with the distance along the plate (x) as
- Aδ∝x^(1/4)
- Bδ∝x^(1/3)
- δ∝x^(1/2)
- Dδ∝x
Explanation
The classical Blasius laminar boundary layer solution gives δ∝√(νx/U∞), i.e. δ∝x^(1/2).
