Bernoulli's Law

In the picture, streamlines of air are passing over a wing(airfoil) and are being analyzed. This law is the general guidelines for flight of an aircraft or airfoil discussing the different pressures that need to be on the top and bottom of the airfoil to generate lift.

Equation: (v^2/2)+gz+P/density

with v=fluid speed
g= acceleration
z= elevation
P= pressure
