Question

If two pieces of paper resembling page from a copy are held parallel to each other and air is blown forcefully through the place in the middle the papers come close to one another Explain this observation from Bernoulli's prinicipal​

Answer 1

Explain this observation from

Bernaulli's principle

an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. ... When the air speeds up, the pressure also decreases. Past the constriction, the airflow slows and the pressure increases.

Answer 2

Explanation,

The pressure difference that forms is responsible for this inward moment of paper to take place.

• Two pieces of paper are held parallel, and the air is blown forcefully through the middle. This removes the air present in between the papers, due to which a low-pressure region is formed on the inside.

• On the outer part of the paper pieces, normal pressure acts. This difference in pressure on both sides of the paper results in an inward force that moves the paper pieces towards the middle.
