Perhaps someone can help with this one.
My brain generally reels reading the lift posts but I do have a question on what the authors are saying below.
The relevant bit is
"The BE is a statement of the conservation of energy. For it to be applied the system must be in equilibrium and no energy added to the system.... A great deal of energy is added to the air.... A 250 ton plane is doing a lot of work to stay in the air."
and the crucial statement:
"We have shown that the pressure and velocity of the air over a real wing in flight are not related by BE."

This seems at odds with people who use Bernoulli to trade off static pressure with velocity when designing real aircraft. These professional plane makers mention no qualifiers as regards work transfer.
Just one example
'Ch 10. The relation between supervelocity and pressure coefficient'
in a book bursting at the seams with Cp plots and much, much more for all airliners from DC-8 on and written by a Fokker man.
Aerodynamic Design of Transport Aircraft
So shouldn't the college aerodynamics professor author at the top of the post be preparing students to go into industry?
