A model airplane has a wing span of 6 ft and a chord (leading edgetrailing edge distance)

Question:

A model airplane has a wing span of 6 ft and a chord (leading edge–trailing edge distance) of 4.5 in. The model flies in air at 60°F and atmospheric pressure. The wing can be regarded as a flat plate so far as drag is concerned.

(a) At what speed will a turbulent boundary layer start to develop on the wing?

(b) What will be the total drag force on the wing just before turbulence appears?
