An airplane moves through air with a velocity of v200 ms, Ask an Expert

Academics

An airplane moves through air with a velocity of v=200 m/s. The flow a line just above the superior face of the wing is compressed to 80% of its original area and the ones under the wing does not compress at all.

1) Discover the velocity of air just above the wing

2) Find the difference in pressure in the air among the superior part of the wing P, and the inferior part of the wing, P'

3) Find the net ascendant force over both wings because of the dissimilarity in pressure, if the area of the wing is 40 m^2 and the density of air is 1.3 kg/m^3.
