(If there is no meniscus, the value is meaningless.) what did you mean? I do not understand.
hydrophobic surface means:
the surface is in nano-sized rough structure.
air is trapped in the roughness during the flow of water, so the water does not stick to the surface and the surface does not hold water.
In fact, only water flows on the surface.
Air is trapped in the spaces between the water and the surface.
I am attaching the hydrophobic surface and velocity profile photo.
