A wide range formula for compression factor function of reduced properties

الملخص EN

This paper presents an effort aimed at developing a new formula to calculate compression factor within acceptable error range.

A formula has been generalized to permit calculation of the compression factor as a function of reduced properties: reduced temperature TRRR and reduced pressure PRRR.

The new correlations show improvement in temperature and pressure range which offers flexibility for estimating compression factor for a wide range of reduced temperature ; TRRR = 1-5 and reduced pressure ; PRRR = 0.5-6.5.

This correlation provides accurate and computationally reliable prediction of the compression factor (Z) with an average absolute error (AAE) 4.6 % for 169 data points.
