The viscous laminar flow of air over a flat plate results in the formation of a boundary layer

Q. The viscous laminar flow of air over a flat plate results in the formation of a boundary layer. The boundary layer thickness at the end of the plate of length L is δL. When the plate length is increased to twice its original length, the percentage change in laminar boundary layer thickness at the end of the plate (with respect to δL) is ____________(correct to two decimal places).

Ans: 41.30 – 41.50
