RE: viscosity of D2O

Geoff,

By now you may have heard this from others, but the viscosity of D20 is
considerably (~25%) higher than for H20. From what Art Rowe said I guess
we'll get some updated values soon, but anyway here are some data I found
for the viscosity ratio, D20/H20 versus temperature:

5 degrees	1.309
10 		1.286
15		1.267
20		1.249
25		1.232
30		1.215
35		1.198

Hi All

I have searched the RASMB archives in vain for a reference to the viscosity
of D2O.  There doesn't seem to be a value in the Rubber Handbook.  While I
presume it is about the same as H2O I would be grateful for something more
definite.

Best wishes
