Question

define nominal thickness of the boundary layer

Answer 1

Answer:

Nominal thickness of the boundary layer is defined as the thickness of zone extending from solid boundary to a point where velocity is 99% of the free stream velocity (U)  This is arbitrary, especially because transition from 0 velocity at boundary to the U outside the boundary takes place ...
