Air flows over the top of an airplane wing, area A, with speed v, and past the underside of the wing with speed vu. Show that Bernoulli’s equation predicts that the upward lift force L on the wing will bewhere p is the density of the air. (Hint: Apply Bernoulli's equation to a streamline passing just over the upper wing surface and to a streamline passing just beneath the lower wing surface. Can you justify setting the constants for the two streamlines equal?)
