SUMMARY

The discussion focuses on calculating the compressibility factor (Z factor) of gases using the Beattie-Bridgeman equation. Key variables include pressure (P), molar gas constant (R), temperature (T in Kelvin), and volume of a mole of gas (V). Empirical constants A, B, and C vary for different gases, and users are specifically interested in O2, He, and Air. The conversation highlights the need for guidance on sourcing the empirical constants and understanding the equation's application.

PREREQUISITES
  • Understanding of the Beattie-Bridgeman equation
  • Familiarity with gas laws and thermodynamics
  • Knowledge of empirical constants for gases

I need to calculate the compressability of several gases as they are being added to a storage cylinder. I would like to use the Beattie-Bridgeman equation as described here.

I need to be able to compute the Z factor (compressability) for a given gas at a given pressure.

I am a bit new to this and need some help to work my way through this.

So here is where I am at (far behind from what I can tell)

P = pressure (this is what we are solving?)

R = molar gas constant (I assume you look this up somewhere)

T = temperature (From what I have read this is in K)

V = volume of a mole of gas (The what?)

A, B and c = empirical constants (I assume these are dirrerent for different gases. Is there a table somewhere?)

I am dealing with O2, HE and Air (assuming .21 FO2 and .79 FN)

Ususally I can figure out complex things like this is I get a shove in the right direction. Thanks

Got the constants and figured out everything.
 
Hi!

I am looking for the same stuff, can you help me on this?
