Does any one know how to calculate the thermal conductivity, thermal capacity, and the thermal differential of differant liquids?
Try posting this in the technical discussion section, you'll prob get faster results

do you mean something like specific heat capacity ( how much energy it takes to raise the temperature by 1 degree C) water is about 1 J /(g x C) I think
J = joules
g = 1 gram
C = 1 degree celcius

The specific heat of water is approximately 4.2 (KJ/(Kg*K)). This is valid for temperatures from 275K to 390K.
Thermal Conductivity of water at 295K is 0.606 (W/(m*K)).
Is this what you're asking for, but for many different fluids? I'm not sure what you mean by thermal capacity and thermal differential, but the best way to get properties of fluids is to look them up in tables.
Note: Data from Introduction to Heat Transfer by Frank P. Incropera and David P. Dewitt, 4 ed. (2002).

and to convert K into C
C= K - 273
unless you have thermometer that reads Kelvin you might need this :)

"CRC Handbook of Chemistry and Physics" is the standard reference source for this kind of data.
It's the industry standard and as such is redilly available at any library.

any physics or chemistry book worth its salt will have that info
