Wilhelmy Plate Method of Surface Tension

A thin plate is utilized to determine equilibrium interfacial and surface tension on the air-liquid or liquid-liquid interfaces. The vertically oriented plate is for the interface and the force is applied to measure the surface tension. This is a universal method which is mainly appropriated for surface tension testing at long intervals. A known perimeter is connected to vertical plate balance and because of wetting, the force is measured.
