Question

Identify the high pressure and the low pressure region.

Answer 1

As you can see from the image, a boy is blowing air into the pipe from one end, and due to that the ball at the other end gets lifted up!

As the boy continuously blows air out of his mouth, a high-pressure zone is created near the bottom of the ball.
This high pressure from the air helps in lifting the ball.

So, we can say that a high-pressure zone is created at region B, and a low-pressure zone is created at region A
