Q:

How do you calculate the compressibility of air?

A:

Quick Answer

Air compressibility is assessed with the compressibility factor calculator using the equation Z=PV(/RT), where Z is the compressibility factor, PV is the pressure and RT is the temperature. This equation solves compressibility for many other gases including ammonia, helium and hydrogen.

Full Answer

The Van der Waals equation shows how intensely gas can be compressed. Compression is dependent on temperature and pressure.

  1. Determine temperature
  2. Determining the constant temperature under which compression will take place is necessary. It provides fixed footing for the calculation.

  3. Determine pressure
  4. Determine the pressure exerted. This too must be consistent.

  5. Run the equation
  6. Run the Van der Waals equation. Feed in the pressure and temperature.
