Question

why does pressure drops when air moves at high speed?

Answer 1

I think you're referring to Bernoulli's Principle.I

magine air above a floor: the air molecules are randomly bouncing about in all directions, and some hit the floor. That's the cause of the air pressure on the floor.

Now imagine that a sideways wind is blowing, parallel to the floor. This shifts some of the molecular motion from downwards to sideways, so fewer air molecules hit the floor (and/or the ones that hit don't hit as hard). This reduces air pressure on the floor.

Answer 2

here is your answer ☞
________

The Bernoulli principle is a restatement of the conservation of momentum. The energy of a stream of air is shared between pressure energy (due to random molecular collisions) and stream flow energy (the shared component of the molecular motion in the direction of the stream).

As the air moves around the wing, it is forced to speed up because of mass conservation. The stream flow energy thus increases, and since the total energy has to remain constant (energy conservation), this must come at the expense of the random molecular energy or pressure.

Therefore, the pressure must drop the faster the stream is accelerated.
