Examples of hydraulic machines are:
PNEUMATIC DEVICES
Examples of pneumatic devices are:
PNEUMATIC DEVICES.
These are devices that use compressed air to do useful work. Some of these devices also use liquids to transmit energy. Examples already mentioned above.
(c) Description and components of some examples of Hydraulic and Pneumatic devices.
(1) Water wheel
