Fig. 4-4. Average absolute relative error in brine density as a function of temperature
for various correlations, based on the brine density database in table 4-1

Figure 4-4 shows the average absolute relative error (AARE) in density
as a function of temperature for several density correlations, for data in
the brine density database in table 4-1. Because the error for different
