Is water the least viscous liquid?
There are some liquids which are less viscous than water. Here’s a sampling of viscosities of fluids from Wikipedia. Note that water is the comparison standard, being assigned a viscosity of 1×10^-3 at some time in the past, although the value has been subsequently corrected by just a bit. viscosity (Pas) ethyl alcohol 0.248 10-3 acetone 0.326 10-3 methanol 0.59 10-3 benzene 0.64 10-3 water 1.0020 10-3 nitrobenzene 2.0 10-3 mercury 17.0 10-3 sulfuric acid 30 10-3 olive oil 81 10-3 castor oil 0.985 glycerol 1.485 pitch 107 http://en.wikipedia.
