when high power transmission is involved then hydraulics is the best option this because there are hydraulic fluid available to suit the various pressure levels. liquids have almost zero compressibility.
in pneumatic system air is the working fluid, too high pressure could compress the air to such an extent to liquify it causing the tubes to crystallize and burst it. air is highly compressible and hence power loss should also be accounted for the compressed air so only low power systems possible here eg: pneumatic door openers .
Air Brakes, Vacuum Pump, Pneumatic Tires and Motors, Pipe Organs, Air Compressors.
If the low-and high speed needed to be the squamous cell system is used. If the power and speed needed to be at least the hydraulic system is used.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
Pneumatic, use of air. Hydraulic, use of oil or other fluid.
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
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".
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.
One instance would be when space is a criteria, on an aircraft for instance.
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
Mechanical, hydraulic and pneumatic are the main ones.

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.
