Coefficient of damping

The coefficient of damping characterizes the faculty of a Liquide to wet a Surface.

Let us suppose that one deposits a drop of this liquid on a surface. If, at the edge of the drop, the liquid makes a Angle \ alpha with surface, the coefficient of damping will be given by:

\ qquad has (cos (\ alpha) - 1)

A being the surface Tension liquid.
