Hello!

What I have understood about surface tension is that it lays a pressure on the surface in proportion to the bending of it, the angular change per meter surface , which has the unit . And pressure has the unit . So surface tension would have the unit , which it has. Now, is it so that the pressure applied to the surface is given by

Where S is the surface tension, and x and y have the unit , so has the unit . is the same as , where is the angle ( for small )
