+## Graphical Representation of Properties
+
+### When is a Graph a Chart?
+
+Graphs plot the relationship between two component characteristics.
+
+A chart has the relationship between the two component characteristics but also plots lines of other
+variables on top of them, allowing them to represent more 'dimensions' of the system.

+### Temperature vs Specific Entropy

+
+The orange line is liquid, the flat blue bit is wet steam, the steep blue bit is superheated steam.

+
+## Transport Properties
+
+Transport properties are of use for working out the flow behaviour.
+
+These are:
+
+- density
+
+    Density is affected by temperature and pressure. We know perfect gases have equation of
+    state but we need to use tables for steam an R134a as they are not perfect gases.
+
+- viscosity
+
+    Viscosity in all fluids varies with temperature.
+    On page 10 of the tables there is viscosity of steam and water liquid stated in dynamic form.
+
+    $$\nu = \frac\mu\rho$$
+
+    (kinematic viscosity = dynamic viscosity / density)
+
+- Prandtl number
+- thermal conductivity
