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.

What is a formula of simple hydraulic press?
P=W/A.a where W is the weight lifted by the ram. A is the area of ram and a is the area of piston or plunger
Why does a toilet plunger able to stick to a wall when you press it?
A toilet plunger can stick to a wall when pressed due to the creation of a partial vacuum between the rubber cup and the wall's surface. When you push the plunger against the wall, the flexible rubber compresses, sealing off the air and forming a low-pressure area. The atmospheric pressure outside the plunger then holds it against the wall, allowing it to stick until enough force is applied to break the seal.
Can you push the plunger all way through the syringe while your thumb presses on the tip of the plunger why or why not?
No, you cannot push the plunger all the way through the syringe while your thumb presses on the tip of the plunger. This is because the plunger is designed to create a seal within the barrel of the syringe, and pressing on the tip prevents the plunger from moving forward. The pressure created by your thumb would counteract the force needed to push the plunger, making it impossible to fully depress it.
What is difference between axial piston pumps and vane pumps?
An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand-alone pump, a hydraulic motor or an automotive air conditioning compressor.A radial piston pump is a form of hydraulic pump. The working pistons extend in a radial direction symmetrically around the drive shaft, in contrast to the axial piston pump.
Can you push the plunger all the way through the syringe while thumb presses on the tip of the plunger?
No, you cannot push the plunger all the way through the syringe if your thumb is pressing on the tip. The pressure from your thumb creates resistance that prevents the plunger from moving fully. Additionally, the design of syringes typically only allows the plunger to move to a certain point, ensuring it doesn't come out completely.
What is difference between piston and plunger?
1-in piston pump uses O-ring 2-in piston pump use metalic piston cylinder 3-piston pump use for expensive service 4-low pressure then plunger pump 1-in plunger pump use gland packing 2-plunger pump use for medium service 3-in plunger pump use in casing,cam and gijan pin 4-high pressure use 1000psi
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 piston and its function?
piston is a plunger that moves ups and down in the engine block.the function of the piston is to compress air mixtures in the engine block
What is a solenoid pump?
It's a type of piston / plunger pump using the principle of an electrical solenoid to articulate the piston.
What is the difference between phenolic piston and steel piston?
Phenolic is a composite material and is used to reduce the transfer of heat from the brake pads to the brake fluid via the piston.
What is the difference between balancing piston and balancing drum in compressors?
They are the same thing.
What is the difference between a Gas turbine engine ignition system and a piston engine ignition system?
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
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

yes
Is there any difference between piston rings of naturally aspirated engine and turbo charge engin?
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
What is a formula of simple hydraulic press?
P=W/A.a where W is the weight lifted by the ram. A is the area of ram and a is the area of piston or plunger
What is single acting hydraulic cylinder?
Single-acting devices consist of a large plunger, or piston, into which oil (or air in a pneumatic cylinder) is pumped.
