List the basic principles of compression and explain how these operate industrial valves.
What will be an ideal response?
The principles of compression include;
• compression decreases volume
• gases and vapors are compressible
• liquids and solids are typically considered to not be compressible
• compression generates heat
• Compression moves gas molecules close together
• Compressed gases will resume their original shape when the pressure is released.
• Compressed gases produce or generate heat because of molecular friction
• The smaller the volume the higher the pressure
• Force ÷ Area = Pressure
• Gas volume varies with temperature and pressure
