Why does wind velocity increase over a wing?
Also I have a bit of a paradox, people explain lift by saying there is a lower pressure region on the top of the airfoil and a higher pressure region on the lower airfoil. Then, they explain that there is a low pressure region due to the increased velocity of air (Bernoulli's).
They also explain that the velocity of air increases due to the low pressure region, surely one has to induce one or the other, or neither would happen? From where the extra energy is provided for kinetic energy of wind to increase?
