One of the most common is the bus or heavy goods vehicle - fitted with air brakes. Similarly the brakes on trains. However there is a huge range of industrial tools, machines and control systems powered by compressed-air.
Nowhere As of now!
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.
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 amount speed put out from any prime mover depends on the amount of energy put into the system. Hence there can be no absolute answer to your question.
Examples of pneumatic products include: drills, grinders (metalworking machinery), pneumatic chip removal guns, hammers, ratchet wrenches, and sanders.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.
Air. Pneumatic systems use compressed air.
A variety of automation systems use pneumatic tubes to move material via puffs of air. Bank systems still use them. In the Denver Airport, large pneumatic tubes move aircraft parts around the terminals.
There are two types of pneumatic systems currently used in naval aircraft
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.
Pneumatic tube systems today are most seen at the drive-through windows of banks. Pneumatic tubes use pressured air to push a sealed object through the system. how do pneumatic truck trailers work?
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.
No they are not all automatic. They do all use comressed air.
both pneumatic & hydraulic systems are applications of fluid powers
The pneumatic system controlled by electronic systems.
Cars don't use pneumatic brakes. Those are generally used on large vehicles like trains.
