6. Pneumatics Word Exercise Answers
Pneumatic control is fast and clean which makes it ideal for use in textile and food industries.
Air is Compressible which means it can be squeezed into a smaller space.
Air holds moisture which causes Condensation (Dew droplets) in the compressed air system.
Because pneumatic components often function with metal to metal moving contact, Lubrication is required and is introduced by the Service Unit which contains a Filter, Regulator and Lubricator.
High pressure air is produced by Compressors. The flow of air is measured as the Free Air Delivery (FAD) in m3 per hour.

7. Hydraulics Word Exercise Answers
Hydraulic control produces extremely large forces which makes it ideal in pressing applications such as car body panels or in lifting equipment such as cranes.
Oil and water is Incompressible, therefore the fluid cannot be compressed.
Fluid generally needs Lubricating (for metal to metal movement), Anti Oxidising (to stop oxidisation) and Anti Foaming (to inhibit fluid foam) properties which are produced using Additives.
Fluid flow is produced by hydraulic Pumps. These pumps are usually positive Displacement devices.
The fluid flow is transferred through Hoses that are Braided (platted) for reinforcement, or steel Pipes, to contain the very high pressures.
