Question:
A model airplane descends in a vertical dive through air at standard conditions (1 atmosphere and 20°C). Th e majority of the drag is due to skin friction on the wing (like that on a flat plate). The wing has a span of 1 m (tip to tip) and a chord length (leading edge to trailing edge distance) of 10 cm. The leading edge is rough, so the turbulent boundary layer is “tripped.” The model weighs 3 N. Determine the speed (in meters per second) at which the model will fall.
