Question:

Classify each of the following features into one of two categories: laminar boundary layer (L), or turbulent boundary layer (T).

a. The flow occurs in smooth layers.
b. The boundary layer contains eddies that mix the flow.
c. The velocity profile can be written with a power law equation.
d. The velocity profile is a function of √Re.
e. The velocity profile can be described with the logarithmic velocity distribution.
f. The boundary layer thickness δ varies as x6/7.
g. The boundary layer thickness δ varies as x1/2.
h. Even when the mean flow is steady, the velocity in the boundary layer will be unsteady.
i. Shear stress is a function of the natural log.
j. Shear stress is a function of √Re.
