An airplane wing of 2 m chord length (leading edge to trailing edge distance) and 11 m

Question:

An airplane wing of 2 m chord length (leading edge to trailing edge distance) and 11 m span flies at 200 km/hr in air at 30°C. Assume that the drag force of the wing surfaces is like that of a flat plate.

a. What is the friction drag on the wing?

b. What power is required to overcome this?

c. How much of the chord has laminar flow?

d. What will be the change in drag if a turbulent boundary layer is tripped at the leading edge?
