Water Evaporation Coefficient

The kinetics of water droplet evaporation have been measured using a cylindrical electrodynamic balance, recording the evolving size of droplets over time. Measurements have been made over a range of temperatures extending from 248 to 293 K. From these data, the vapour pressure of water (including under super-cooled conditions) has been inferred. A constraint has also been placed on the value of the evaporation coefficient.
