Bernoulli’s Principle

An airplane flies on a level path . There is a pressure difference of 520 Pa between the lower and upper surface of the wings . The area of each wing surface is about 170 m^2 . The air moves below the wings at a speed of 80.1 m/s .

a) Estimate the weight of the plane .

b) Estimate the air speed above the wings .
