The deviations of the correlations were r = 1.47% for the water
side and r = 0.90% for the CO2 side. The deviations were small; a
very small difference was found between correlations obtained
using logarithmic mean temperature difference and those obtained
using generalized mean temperature difference. Therefore, the
simulation calculations with a small temperature difference
yielded the more accurate prediction, although the fluid properties
varied rapidly around the pseudo-critical point.
