Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
Does atmospheric pressure act on both sides of the plunger in the sealed syringe?
Yes, atmospheric pressure acts on both sides of the plunger in a sealed syringe. The pressure outside the syringe applies force on the outer surface, while the pressure inside the syringe is influenced by the contents within. If the plunger is pushed or pulled, the pressure difference between the inside and outside can create a force that moves the plunger. However, in a sealed environment, the pressure inside can change based on the volume of the fluid inside the syringe.
What is the pressure inside an inverted hollow cylinder in water and how to calculate it?
The pressure inside an inverted hollow cylinder in water is equal to the pressure at the depth of the cylinder's centroid multiplied by the specific weight of water. To calculate it, use the formula: pressure = (specific weight of water) * (depth of centroid of cylinder).
Why pressure inside of cylinder must equal to pressure outside?
For an engine to work efficiently, the pressure inside the cylinder must be equal to the pressure outside to allow for proper combustion and expansion of gases. This ensures that the engine can generate the necessary power to move and operate effectively. Any difference in pressure between the inside and outside of the cylinder can lead to issues such as poor performance, engine knock, or even damage to the engine.
What is the cylinder pressure?
Cylinder pressure refers to the pressure of the fuel-air mixture inside the combustion chamber of an engine. It is a critical parameter that influences engine performance and efficiency, with higher cylinder pressure generally leading to more power output. Monitoring and optimizing cylinder pressure is key to maintaining engine health and performance.

How does a syringe use atmospheric pressure?
Oh, dude, it's like this: when you pull back the plunger on a syringe, you decrease the pressure inside, creating a pressure difference with the atmosphere. So, the higher pressure outside pushes the liquid or medication into the syringe. It's basically like nature's way of helping you get that flu shot without even thinking about it.
What is piston diameter?
A piston is a plunger, or a plug that moves inside a cube, a cylinder. The piston diameter is the diameter of this plunger/plug. It's a tiny bit smaller than the diameter of the cylinder the piston moves in.
What is the difference between piston and plunger?
The difference between a piston and a plunger may be understood if you observe what forms the seal that precludes the fluid from passing either the Plunger or Piston. The 'piston' is a steel block equipped with elastomers that makes wall contact with the cylinder wall. As it moves inside the cylinder it wipes the wall and displaces the entire content of the cylinder. In this case the seals form part of the piston. The 'plunger' is a steel block that moves through a hole that is equipped with elastomer seals. The plunger displaces a portion of the cylinder contents, i.e., the volume of the plunger that enters the cylinder. The plunger does not wipe the walls of the cylinder. The seals, in case, are a part of the cylinder block. Umair Aslam Mechanical Engineer PARCO, Pakistan
Why does a syringe go down when you push it then pop back up again?
When you push down on a syringe plunger, you compress the air or liquid inside, creating increased pressure. Once the plunger is released, the pressure inside the syringe decreases, allowing the plunger to return to its original position due to the force of the surrounding air pressure or liquid pushing back against it. This is an example of how pressure dynamics in a closed system work, causing the plunger to pop back up.

When using a tuberculin syringe do you measure using the edge of the plunger where it touches the syringe or the tip of the rounded edge of the plunger?
Measure to the edge of the plunger (or piston) where it touches the inside of the syringe cylinder. http://www.northcumbriahealth.nhs.uk/palliativecare/clinical/syringe/05.php
How do moving molecules cause pressure inside a cylinder of butane?
Moving molecules in a cylinder of butane collide with the walls of the cylinder, creating a force per unit area known as pressure. The more molecules and the faster they are moving, the higher the pressure inside the cylinder.
What is the gas pressure inside the cylinder?
The gas pressure inside the cylinder is the force exerted by the gas on the walls of the cylinder. It is measured in units such as pounds per square inch (psi) or pascals (Pa).
How would you find the surface area of a cylinder with a cylinder bored out of it?
if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder
What crumbles the plastic bubble when you apply force to the plungder?
a plunger crumples when pressure is applied because the presume pushes out the air creating a vacuum and the air pressure on the out side is more than the pressure on the inside creating a suction effect and causing it to crumple
