Question

proof that fluid exerts pressure ​

Answer 1

Answer:

Fluids are made of a large number of very small particles, much too

small to see. These particles are in constant, rapid motion. They bump

into one another. They bump into the walls of any container that holds

them. They bump into objects in the fluid.

As the particles of a fluid bump into an object in the fluid, they

apply forces to the object. The forces, acting over the object’s surface,

exert pressure on the object. When the pressure in a fluid increases, the

vparticles bump together more frequently. This increases the pressure

on objects in the fluid.

The pressure a fluid exerts on an object in the fluid is applied in

all directions. That is because the particles that make up the fluid can

move in any direction. These particles exert forces as they bump into

objects in the fluid. The picture shows how water exerts pressure on a

diver who is underwater. Notice that the arrows point in different

directions. That is because the water is pressing all around the diver,

not just from above.

TO PROVE THIS,

Take an empty plastic bottle or a cylindrical container. You can take a used plastic bottle. Drill four holes all around near the bottom of the bottle. Make sure that the holes are at the same height from the bottom. Now fill the bottle with water.� You will observe that liquid coming out of the holes fall at the same distance.

Answer 2

$\huge{Answer}$

Take a plastic water bottle and fill it with water. Make a tiny hole with a sharp needle at any point below the free surface of water. Notice the water flows out through the hole now place your finger on the hole you will feel the thrust of water acting on your finger .

This proves that water contained in the bottle exerts pressure. And hence water exerts pressure.
