As a consequence of being a … WebEven if precursors of this field such as Jurin or Laplace already date back to the 18th century, describing surface tension effects from a mechanical perspective is very recent. The originality of this book is to consider the effects of capillary bridges on solids, including forces and torques exerted both statically and dynamically by the ...
WebThe surface tension γ is defined as the magnitude F of the force exerted tangential to the surface of a liquid divided by the length l of the line over which the force acts in order to maintain the liquid film. γ =F/l (1) In this experiment we will determine the surface tension of water by capillary rise method. Websurface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. …
