Compressibility

Written by Jerry Ratzlaff on . Posted in Thermodynamics

The compressibility factor is a dimensionless factor independent of the quantity of gas and determined by the character of the gas, the temperature, and pressure.

formula

\(Z=\frac{P \cdot V}{n \cdot R \cdot T}= frac{M \cdot p_a \cdot V}{m \cdot R \cdot T}\)

Where:

\(Z\) = compressibility factor

\(\beta\) (Greek symbol beta) = compressibility

\(p_a\) = absolute pressure

\(V\) = volume

\(n\) = moles

\(m\) = mass

\(M\) = molecular mass

\(T\) = temperature

\(R\) = universal gas constant
