Yes - but not mixed.

Pneumatic systems have more "give" (gas is compressible).

Note that the power brakes on your car consists of both.

Pneumatic braking system utilizes compressed air to stop the motion in vehicles.

Depth and temperature affect pressure by increasing the pressure as the depth increases. As depth increases, temperature often falls.

not quite, it depends on the pressure of system,

but hydraulic tends to be high or could be very high pressure,

and pneumatic is often lower pressure.

the low grade rated pressure hose/ pipe would fail and burst/ causing injury.

Central pneumatic is a company and they sell tools of the power sorts, including: air compressors and air hoses. The products they sell are mainly bought by machinists and shops for use in industry.

The price range for new a pneumatic press is normally between two thousand dollars and two thousand five hundred dollars. They can be purchased on Amazon.

A pneumatic drill, also known as jackhammer or demolition hammer, can be used to break up concrete, pavement and rock. It drives an internal hammer up and down.

Stress has the same dimensions as pressure: force per unit area. In the SI, therefore (or in other MKS systems), the units would be newtons / meter2.

The tanker is loaded with lpg or any other liquid . By pushing the liquid with high pressure pneumatic nitogen or any other inert gases.Inert gas will be pushed through the vapor line and liquid starts to comeout from liquid line to other empty source.

Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.

A clamp or vice that uses pneumatic power to close and hold pressure upon a part. Pneumatic means air. In this context compressed air.

The Pronex Pneumatic Cervical Traction device works by supporting the head and neck between 2 cushions that are then inflated by air providing an even stretch to the cervical discs. Pressure is increased and decreased gently by the patient squeezing a bulb inflator so they have full control of their own traction.

A current signal is converted into a pneumatic signal with a Current-to-Pneumatic Converter. The converter allows a safe and proportional output to ensure a seamless conversion.

Pneumatic systems are most commonly used in automatic doors, be it in buildings or buses. They're used in production lines as a means to get the items around the line easily and quickly.

Hydraulics aren't commonly used in society, more industry.
They're used in heavy duty earth movers, such as JCB's, to enable them to move the large weights that they do.
