Surface tension
Reference data et engineering information about surface tension pour fluid mechanics applications.
surfacetension
Overview
Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. It arises from the cohesive forces between liquid molecules at the interface.
