Naveed:

May I ask why you require a sharp-resolution T-S diagram of water? Unlike the days of yesteryear when students like myself had to beg and steal for T-S diagrams, today you have a multitude of accurate computer programs and databases available for your use. Unless you are teaching Thermo cycles and processes or perhaps trying to understand a cycle or process, there is no need for the diagram anymore. A lot of people have them hanging from the wall as a decoration.

I recommend you go to the National Institute of Standards and Technology (NIST), an official branch of the US government, operates a The Website at:

http://webbook.nist....hemistry/fluid/

This website gives FREE thermodynamic data on: Thermophysical Properties of Fluid Systems.
Accurate thermophysical properties are available for several fluids - including water. These data include (in any unit):

Density
CP
Enthalpy
Internal energy
Viscosity
Joule-Thomson coefficient
Specific volume
CV
Entropy
Speed of Sound
Thermal conductivity
Surface tension (saturation curve only)

So, if you are working with a difficult-to-read T-S diagram, you can obtain the accurate values and assign them to the diagram. Or, if you have the time and ambition, you can draw your own diagram from the data generated by NIST.

I hope this helps.

Fortunately we have Google nowadays!

What about this one: http://www.conestoga.....T-s Water.jpg

Great Contribution. Thanks.

I'm going to frame this one to go with my other T-S diagrams.

I just got to your ruptured tube thread and I'm working on a response. I'll try to get something.
