Many, many places. Good examples of hydraulic systems include automotive brakes, and the control systems of large aircraft. Pneumatic systems include many types of tools found in an automotive repair shop. Both systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics give high forces with low losses, thanks to the virtual incompressibility of hydraulic fluids. Pneumatics are usually less efficient, though simpler since the "resevoir" in the circuit is the atmosphere. That eliminates return piping and leakage problems.

The barleycorn measure is used in traditional systems of measurement as a unit of length equal to one-third of an inch. It is commonly used in the UK and other countries for measuring small lengths, especially in industries like shoemaking and textiles.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
An airbag in an automobile primarily uses a pneumatic system, as it relies on gas inflation to deploy rapidly during a collision. The airbag is typically filled with nitrogen or another gas from a canister, which expands to fill the bag upon impact. While hydraulics can be used in various automotive systems, they are not involved in the airbag deployment process. Thus, airbags primarily function through pneumatic mechanisms rather than hydraulic ones.
pneumatics are used only in low power applications hydraulics are used in medium to high power applications.
There are two types of pneumatic systems currently used in naval aircraft
Air pressure is used as ejector for the sand blasting.
I think it is because hydraulic systems are stronger than pneumatic systems. if you know that is wrong then get an expert. : )
No. There are a few reasons why a pneumatic control valve can not be used with hydraulics applications. Firstly, pneumatic seals are incompatible to the chemical properties of hydraulic oils and they do not have the strength to accommodate the high pressures produced by a hydraulic system. Secondly, pneumatic valves are not designed for high pressure operation and the component would get damaged, burst or crack. Finally, the tolerances within pneumatic components would allow by-passing due to the slacker tolerances compared to hydraulic components. By-passing causes all sorts of problems by itself: Over-heating, leaking, internal structure damage of the component.
Hydraulic systems may be used to open and close drawbridges.
Solids do not flow at room temperature, so they are not practical for use in hydraulics. When a gas like air is used in a system similar to hydraulics, it is called pneumatics. Sometimes hydraulic systems use both, like in an automobile lift.

Yes - but not mixed. Pneumatic systems have more "give" (gas is compressible). Note that the power brakes on your car consists of both.
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
