Contribution for a Very Accurate Determination of The Water Vapor Pressure Curve

摘要：

In this work we start a study where the purpose is to investigate the relation between temperature and pressure in the case of pure water with the best uncertainty level in the temperature range between 173 K and 373 K. We present here our first step in this study, i.e. the first measurements, obtained thanks to a gas control heat pipe (GCHP), in the temperature range between 350 K and 385 K. These measurements are compared to data from literature and a preliminary uncertainty budget is proposed.
