The apparent constriction of the liquid. Physics.

The theoretical formula derived to calculate the surface tension of the liquid. Data from ref pounds confirm the formula for the 64 liquids in the range of T -253 to 200 degrees Celsius. Formula is obtained within the validity of the equation of Clapeyron - Mendeleev. The physical relationship of the phenomenon confirms the common ratio of internal energy and surface tension of the liquid. The formula is obtained simply and clearly. There are integral in the derivation ofthe formula! The physical model has been written and published in Russian Gennady G. Khaydarov contributions in 1983. A similar physical model was published by Victor F. Weisskopf in 1985. For more information on the model surface tension is in Wikipedia (Russian), articles and Wikibooks (Russian) in detail.
