| Abstract | ||
| 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 TR and reduced pressure PR. The new correlations show improvement in temperature and pressure range which offers flexibility for estimating compression factor for a wide range of reduced temperature; TR=1-5 and reduced pressure ;PR=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. | ||
