Use Bernoulli's equation to estimate the upward force on an airplane's wing if the average flow speed of air is 195 m/s above the wing and 162 m/s below the wing.

• Physics -

You need the wind area for the force. The Bernoulli equation will only give you the pressure difference between the top and bottom of the wing.

You also need the air density, which varies with altitude.
