Enthalpy-Entropy Diagram for Water

​
show lines of constant:
pressure
temperature
quality
grid lines
phase envelope
This Demonstration shows an enthalpy-entropy (
H
-
S
) diagram for water. Use the checkboxes to display lines of constant pressure
P
(purple), temperature
T
(green) or vapor quality
q
(blue). Check "phase envelope" to show saturated liquid (magenta), saturated vapor (orange line) and the critical point (black dot). You can also show the grid lines.

diagrams are useful for showing reversible and irreversible adiabatic compression (or expansion) processes, as shown in the screencast video at[1].
