Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.
Meter in and meter out are terms commonly used in hydraulic systems to control the flow rate of fluid. In pneumatic systems, flow control valves such as needle valves or flow restrictors are used to regulate the speed of the air flow. These components are designed specifically for pneumatic applications due to the differences in fluid properties and system requirements between pneumatic and hydraulic systems.
Prisms have two parallel and congruent bases connected by rectangular lateral faces, while cylinders have two circular bases connected by a curved lateral surface. Prisms have flat sides and edges, while cylinders have a curved surface.
A pneumatic test is a type of pressure test where the vessel is pressurized using air or another gas to check for leaks or structural integrity. An air test is a specific type of pneumatic test where only air is used as the test medium. In both tests, the pressure vessel is pressurized, but the distinction lies in the specific medium used for pressurization.
Water pressure is the force exerted by water molecules against a surface, while air pressure is the force exerted by air molecules against a surface. In a hydraulic system, water pressure is used to transmit force and control movement, while air pressure is typically used for pneumatic systems. Water pressure is generally higher and more consistent than air pressure, making it more suitable for heavy-duty applications in hydraulic systems.

There are many differences, and here are a few: Pneumatic systems use gasses which are compressable - hydraulic uses liquids that are non-compressable. Hydraulics' motion is slow and smooth - pneumatics' motion is quick. Pressure can range from 500 to 5000 psi - pneumatics operate at around 100 psi.

hydraulic is liquid based, pneumatic is air.
They are both pressurized fluid systems. They both use pumps to pressurize the fluid. They both use piping to contain the fluid, and they both drive motors and cylinders.
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.

the main difference between hydraulic and pneumatic system is that hydraulics uses fluid to power their system and pneumatic uses air (in that case air is not a fluid) All matter is made up with all particles. thanks you can see more answer in this web i put these all answer.
It all comes under Fluid dynamics/mechanics, and it's the same set of symbols for circuits. Many hydraulic symbols will include a drain to the tank. Pneumatic circuits use the atmosphere as their "tank".
Pneumatic system is operated by compressed air while hydraulic system is operated with pressurised hydraulic oil or any type viscous oil. Hydraulic systems can usually produce higher control forces and work under extreme operating conditions. This is the system that is primarily used on aircraft to move control surfaces and engine controls. You can often classify pneumatic systems because they have a pump (gas pump) and hydraulic systems have a piston. That is the difference. Also, pneumatic systems are louder because it is a gas under pressure. 1. By definition, hydraulics is used in controlling or harnessing power with the use of pressurized fluids whereas pneumatics studies how pressurized gases influences mechanical motion or movement. 2. Hydraulics uses an incompressible fluid medium like oil whereas pneumatics uses a compressible gas like air. 3. Hydraulic applications demand greater pressures during operations that reach thousands of pounds per square inch whereas pneumatic applications only require 100 psi pressures more or less. 4. Most hydraulic applications generally use bigger components that pneumatic applications. 5. Hydraulic systems are generally more difficult to operate compared to pneumatic applications
