Documentation - water with temperature-dependent density

[carlesRT]

I think section Limitations Specific heat capacity, thermal conductivity and viscosity are constant. Water is modeled as an incompressible liquid. There are no phase changes. is wrong.

Dynamic Viscosity is defined with
eta := density(state)*kinematicViscosity(state.T);

and the kinematic Viscosity with
if T < 278.15 then -(4.63023776563e-08)_T + 1.44011135763e-05
else
1.0e-6_Modelica.Math.exp(
-(7.22111000000000e-7)_T^3 + 0.000809102858950000_T^2
- 0.312920238272193*T + 40.4003044106506));

It was probably copied from Media.Water. In case I did not missunderstood the code I would be good to correct the docu and add a plot (viscosity against T)

@carlesRT
You are right about the error in the documentation. It would be great if you can make a pull request against the branch issue487_waterDocumentation
