Abstract

A reduction formula for the calculation of the specific volume v at any temperature T and any pressure P is derived; it consists of the two equations:

The parameters ξ, ζ and ψ can be easily calculated from values in the literature, and therefore only a volume‐temperature curve at atmospheric pressure has to be measured.
