3.4.4 beggs_brill - Beggs-Brill equation of state
z = beggs_brill(ppr, tpr)

Computes the compressebility factor Z using the Beggs-Brill method using the pseudo-reduced pressure and temperature.

Arguments

ppr

Pseudo-reduced pressure Ppr.

tpr

Pseudo-reduced temperature Tpr.

Returns Compressebility factor Z.

Possible Warnings

Beggs-Brill not applicable to Tpr < 0.92

The Beggs-Brill equation of state is normally not applicable to Tpr< 0.92.
