The saturation lines define the regions of
interest as shown in the diagram, being the Compressed Liquid region to
the left, the Quality region enclosed by the saturation lines, and the Superheated
region (which also includes the Transcritical region) to the right of
the saturated vapor line and above the critical point. We will use Property
Tables associated with the regions in order to evaluate the various
properties. Notice that we have provided property tables of steam, Refrigerant
R134a, and Carbon Dioxide, which due to environmental concerns involving R134a
is likely to become the refrigerant of common usage in the future.
