Hello everybody,<br><br>
I have checked the NIST website data
(<a href="http://webbook.nist.gov/chemistry/fluid/" eudora="autourl">http://webbook.nist.gov/chemistry/fluid/</a>)
for D2O at atmospheric pressure against the equations 6, 6a & 6b
reported by Matsunaga & Nagashima (J. Phys. Chem. Ref. Data
12:933-966, 1983), and the agreement is excellent. Moreover, the website
is very handy to use. Instead, the values reported in the
<a href="http://physchem.kfunigraz.ac.at/sm/Service/Water/D2Ovisc.htm"><font face="arial" size=2>http://physchem.kfunigraz.ac.at/sm/Service/Water/D2Ovisc.htm</a>
</font>website are different, and since they don't report the source, I
would advise against using them.<br><br>
Cheers - Mattia<br><br>
PS - For those that might be interested, I can provide an Excel
spreadsheet for computing the viscosity and density of D2O at atmospheric
pressure from 4 to 100 °C, based on the above reference and in
near-perfect agreement with the NIST data.<br><br>

and Others,</font><br>
<br>
<font face="arial" size=2>First thing I must mention: look up the CRC
handbook of chemistry and physics (search result is attached, the uthscsa
should have a membership for the online version...), use the NIST
chemicals database/website (address:
<a href="http://webbook.nist.gov/chemistry/">http://webbook.nist.gov/chemistry/</a>,
results are attached) and finally, just google untill you have what you
were looking for (results are attached, from:
<a href="http://physchem.kfunigraz.ac.at/sm/Service/Water/D2Ovisc.htm">http://physchem.kfunigraz.ac.at/sm/Service/Water/D2Ovisc.htm</a>).
Good luck with your experiments, greetings and best wishes,
laterrrrrrrrrrrrrrrrr</font><br>

<font size=2>Greetings all,<br><br>
We are looking for data showing the density and viscosity of D20<br>
especially at 20C. If anyone can point us in the right direction, we
would<br>
be most appreciative.<br><br>
Thank you,<br><br>
Virgil<br>
