According to Bernoulli's Principle, what happens to air pressure as velocity of airflow over a wing increases?
Why →
Bernoulli's Principle states that in streamlined flow, as fluid velocity increases, pressure decreases. Air flowing over the curved upper wing surface accelerates (longer path), creating lower pressure above. Slower-moving air below creates higher pressure, and this differential produces lift. The same principle applies to propeller and rotor blades shaped as airfoils.The trap →
"Pressure increases with velocity" is the common wrong instinct. The relationship is inverse and counterintuitive. "Pressure remains constant" ignores the velocity change entirely.SOURCE → PHAK Chapter 4, Principles of FlightCHECKED APR 21ACS IV.A.K1MED
