# Beggs-Brill: Beggs and Brill correlation In zFactor: Calculate the Compressibility Factor 'z' for Hydrocarbon Gases

## Description

Calculate the Z factor with the Brill-Beggs correlation

## Usage

 `1` ```z.BeggsBrill(pres.pr, temp.pr, tolerance = 1e-13, verbose = FALSE) ```

## Arguments

 `pres.pr` pseudo-reduced pressure `temp.pr` pseudo-reduced temperature `tolerance` rounding tolerance to avoid rounding readings that are in the middle of the grid. "tolerance" adds flexibility in deciding point closeness. `verbose` print internal

## Examples

 ```1 2 3 4 5 6``` ```## one single z calculation z.BeggsBrill(pres.pr = 1.5, temp.pr = 2.0) ## calculate z for multiple values of Tpr and Ppr ppr <- c(0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5) tpr <- c(1.3, 1.5, 1.7, 2) z.BeggsBrill(pres.pr = ppr, temp.pr = tpr) ```
