1.4. Physical fundamentals



The condition of compressed air is determined by the 3
measures of thermal state:

    T = Temperature
    V = Volume
    p = Pressure



constant volume
isochore compression
This means:

Volume constant (isochor)
Pressure and temperature variable


When the temperature is increased and the volume remains
constant, the pressure rises.




constant temperature
isotherm compression
Temperature constant (isotherm)
Pressure and volume variable


When the volume is reduced and the temperature remains
constant, the pressure rises.



constant pressure
isobar compression
Pressure constant (isobar)
Volume and temperature variable


When the temperature is increased and the pressure
remains constant, the volume increases.
