Question:
The wing on a Piper Cherokee general aviation aircraft is rectangular, with a span of 9.75m and a chord of 1.6m. The aircraft is flying at cruising speed (141 mi/h) at sea level. Assume that the skin friction drag on the flat plate of the same dimensions. Calculate the skin friction drag:
(a) If the flow were completely laminar (which is not the case in real life?)
(b) If the flow ere completely turbulent (which is more realistic) Compare the two results.
