Use the steam tables in the Appendix and make a plot to scale of
a) a T-v diagram showing a constant-pressure line at 400 kPa,
b) a P-v diagram showing a constant-temperature line at 200°C. Include a point in the subcooled region and a point in the superheated region. Observe the distortions of the various diagrams in this text. The distortions are necessary to show the various regions, as the diagrams of parts (a) and (b) should show.
