Find the pressure difference on an airplane wing if air flows over the upper surface with a speed of 123 m/s, and along the bottom surface with a speed of 109 m/s.

If the area of the wing is 31 m2, what is the net upward force exerted on the wing?

Step 1

Apply Bernoulli’s theorem between upper and lower surface of an airplane

Step 2

Then pressure difference on...
