Beattie-Bridgeman Real Gas Model

AI Thread Summary
To calculate the compressibility of gases using the Beattie-Bridgeman equation, key variables include pressure (P), the molar gas constant (R), temperature (T in Kelvin), and the volume of a mole of gas (V). Empirical constants A, B, and C vary for different gases, and tables for these constants can be found in scientific literature. The discussion involves calculating the Z factor for gases like O2, He, and air, with air composition noted as 21% O2 and 79% N2. Participants express a need for guidance in applying these concepts effectively. The conversation emphasizes the importance of understanding each variable and finding the necessary constants for accurate calculations.

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?
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Raman Spectroscopy help'

I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
