Why is it harder to breathe if there is air being blown into our face?
In: Biology
It really does have to do with air pressure. Bernoulli’s principal states that as the velocity of a fluid (air) increases, its internal pressure decreases. So, when you try to inhale air that is moving at a high velocity across your face, you are not dealing with the usual14.7 psi atmospheric pressure, it is much lower. Side note- that’s also how airplanes fly, wings are shaped so the air on top is moving faster than air on bottom, making the pressure below the wing higher than that above; aka “lift”.
