Before revision: The force on the plate due to wetting is measured using a tensiometer or microbalance and used to calculate the surface tension () using the Wilhelmy equation: where is the wetted perimeter (), is the plate width, is the plate thickness of the Wilhelmy plate and is the contact angle between the liquid phase and the plate.
