Question

application of pressure

Answer 1

Some applications of syringe.

▶Strips of the bag are broader.

Some handbags has a thin strap. The thin strap contact with the shoulder produced high pressure caused our shoulder felt pain. The smaller the surface area of the handbag strap, the higher the pressure produced. Use the handkerchief that is used to increase the surface area of the thin strap. The larger the surface area of the handbag strap, the lower the pressure produced.

▶Nails with sharper tip.

If we take a nail whose tip is blunt and When a force is applied to hit the nail, the nail does not buried into the table. This is because by the large area of the nail tip in contact with the table produce low pressure. The larger the tip area of the nail, the more time taken to completely immerse the nail to the table. Next, we take a nail whose tip is sharp. The small area of the nail tip in contact with the table produce high pressure and make hitting the nail into the table become easier. The smaller the tip area of the nail, the less time taken to completely immerse the nail to the table.

▶case of syringe

When we pull the plunger out on a syringe it causes the volume within the chamber to increase. As we know, this causes the pressure do the opposite, which creates a vacuum attempting to re-pressurize back to atmospheric levels. Since the only fluid available on the other side of the needle tends to be a liquid such as blood, which gets sucked into the chamber, reducing the volume and increasing the pressure back to where it wants to be.

▶ In cans

We know that before we spray a can of paint we are suppose to shake it up for a while, listening as a ball bearing rattles around inside. The can is sealed, preventing this gas from boiling and turning into a gaseous state. That is, until we push down the nozzle. The moment the nozzle goes down, and the seal is released, there is now an escape route. The propellant instantly boils and expands into a gas and pushes down on the product trying to escape the high pressure, and expand it’s volume the atmosphere where there is less pressure. This forces the product to shoot out from the nozzle, and we have a coat of paint.

▶ others

From drinking straws to flying an airplane, we are surrounded by pressure. When a vacuum cleaner is switched on, it sucks out the air inside the cleaner, causing the pressure inside the cleaner to become low.

Answer 2

$\huge {\rm{\orange{Answer:-}}}$

Applications of pressure:-

1) A syringe consists of a tight-fitting piston which moves in a cylinder, with a nozzle at one end also works with the help pressure.

2)When air is sucked out of a drinking straw ,the air pressure inside it decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

3)A vacuum cleaner has a fan inside that creates a low pressure inside the device . Consequently,air and dirt particles are sucked into the device.

4)Siphon is only a rubber cylinder utilised for exchange fluid with the help of pressure.
