Once two of the three reduced properties are found, the compressibility chart can be used. In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found.
The compressibility of water is a function of pressure and temperature. At 0 °C, at the limit of zero pressure, the compressibility is 5.1 × 10 −10 Pa −1. At the zero-pressure limit, the compressibility reaches a minimum of 4.4 × 10 −10 Pa −1 around 45 °C before increasing again
Compressibility is an important factor in aerodynamics. At low speeds, the compressibility of air is not significant in relation to aircraft design, but as the airflow nears and exceeds the speed of sound, a host of new aerodynamic effects become important in the design of
Includes a chart of compressibility factors versus reduced pressure and reduced temperature (on last page of the PDF document) Theorem of corresponding states on SklogWiki . This thermodynamics -related article is a stub .
These dimensionless thermodynamic coordinates, taken together with a substance's compressibility factor, provide the basis for the simplest form of the theorem of corresponding states. [1] Reduced properties are also used to define the Peng–Robinson equation of state, a model designed to provide reasonable accuracy near the critical point. [2]

The Carr index (Carr's index [1] or Carr's Compressibility Index [2]) is an indicator of the compressibility of a powder.It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula =, where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after "tapping down".
