I always thought Bernouilly's Law was a law on pressure, not lift. It says that the sum of static and dynamic pressure (and not lift) within the same large body of air (gas of course) is constant. Lift only occurs if there is a pressure differential over a body (eg a wing). If the velocity differs in two situations (eg the top and the bottom of a wing) within the same overall body of air, then according to Bernouilly's Law there will be two different pressures acting on that body, resulting in a force. That is lift. Maybe I'm wrong, but that's because it's been long a time since I studied these fascinating phenoma.
