zFactor (version 0.1.9)

z.Papp: Papp correlation

Description

Calculate the Z factor with the Papp correlation

Usage

z.Papp(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

# NOT RUN {
# Example 1
## one single z calculation
z.Papp(pres.pr = 1.5, temp.pr = 2.0)
# Example 2
## 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.Papp(pres.pr = ppr, temp.pr = tpr)
# }
