The given work is devoted to an experimental research properties of the liquids considered liquids of Newton, at which initial voltage of shift close the experimental research is resulted in zero. Together with definition of a superficial tension of liquids the present work also is devoted to measurement of small initial voltage of shift. As object of research three liquids water, spirit and glycerin have been chosen. For these liquids the initial voltage of shift concerning a glass, a polyethylene tube and a metal surface was defined.

In work the border of applicability of the equation of Newton for viscous liquids for water, spirit and glycerin is found experimentally out. From measurement of a superficial tension of water average minimal importance of factor of a superficial tension – 0,024 N/m, and average maximal importance – 0,057 N/m is revealed. Unfortunately, calculation of a dead zone from the theory of linear fluctuations with friction does not give, observable in experiments, a range of values of height of a raising of a liquid in a capillary. It is possible, that in this case there is the reorganization of superficial molecular layers resulting in change of a regional corner.
