Please identify what is wrong with my reasoning and help. There is a liquid in a container.
it's topmost layer is stationary , macroscopically as seen from outside.
This means there is no net force on the topmost layer.
On any particle of the topmost layer, pressure P atmospheric acts from all directions , including from the liquid beneath.
Where is there any chance of unbalanced forces to cause surface tension?
I think that forces are balanced only because there is surface tension in the first place Is this correct??.. please explain how surface tension is balancing the forces if it is the case??
Q2.) If I increase pressure on the free surface of the liquid, The pressure inside increases by the same amount. This implies that an increase in pressure, i.e., extra force applied on the surface of liquid is being balanced by the layer of liquid just below the surface and not surface tension.. Is the above statement correct or is it that some proportion of increased pressure is balanced by increase in surface tension too??
Is there any good book that has logically complete theory of fluids??
Also if you are interested /capable please answer this.. I would be very happy.. Surface Tension-- Sessile drop
