Research Abstract

This research project has been performed to determine the evaporation coefficient by sound resonant experiment and construct an experimental formula for determining evaporation coefficient. The results can be summarized as follows: (1) Determination of evaporation coefficient of water by sound resonant experiment between 295 K and 315 K, (2) Measurement of temperature dependence of evaporation coefficient, (3) Consideration of measurement error caused by temperature dependence of the sound source.
