FIELD: physics.
SUBSTANCE: liquid droplets are deposited onto a solid horizontal surface. The height of the peak of the droplet and the radius of the contact spot of the droplet with the substrate are measured from the image of the droplet. The surface tension coefficient and the wetting angle are determined with given accuracy by solving equilibrium equations. There are no restrictions on the size of the droplet and wetting angle values.
EFFECT: simple measurement procedure and high accuracy of results.
