Thanks Juan, can you answer a question about the spreadsheet...what kind of crazy unit is the density and conductivity given in? Also, I do not see the latent heat values for phase changes...
Looks like a good sheet thought...are you familiar with how it works? Can you add fluids knowing the fluid properties?
I haven't noticed that there were no latent heat values, sorry. I found the page looking for viscosity and specific heat at different temperatures. I think that those crazy units are related with the API gravity (Petroleum standars), in the first sheet.
About the density, I just took the specific gravity and multiply it by the water density.
Also, to add a fluid you can add (or replace) properties in the first sheet: API grav, and viscosity at 104°F and 212°F (you can easily find those). Maybe the density is related to petroleum standars.
