Abstract
An evaporimeter is formed of a capillary tube hydraulically coupled to a sheet of filter paper to form a capillary system establishing hydraulic continuity of liquid between the tube and the surface of the filter paper. The rate of evaporation from the surface of the filter paper of a liquid such as water in the tube and filter paper is measured by the water front movement in the tube as the water is drawn from the tube to replace the evaporated water.
