1. The problem statement, all variables and given/known data (a) Find the pressure difference on an airplane wing where air flows over the upper surface with a speed of 117 m/s, and along the bottom surface with a speed of 104 m/s. (b) If the area of the wing is 38 m2, what is the net upward force exerted on the wing? 2. Relevant equations i have no clue. 3. The attempt at a solution I think my teacher might have left off a part. I don't know how you could find a change in pressure without maybe the height of the wing. I guess you can assume the density of air is about 1.29 kg/m^3 and g=9.81 m/s^2. Is there a way to find it with just the 2 velocities?
