Koutsoyiannis has just derived an equation to possess calculating saturation steam tension off drinking water according to the Clausius–Clapeyron picture and you will revealed that the fresh new cousin huge difference in the source datasets was quick of ?40° to 50°C (Koutsoyiannis 2012)
There’s been much browse into creating this new saturation vapor stress. Bosen provided a formula to own figuring brand new saturation vapor tension of water with sensible accuracy regarding temperatures are priced between ?51.1° to help you 54.4°C (Bosen 1960). Langlois put up an excellent fractional formula getting computing the brand new saturation vapor stress from drinking water and you will compared the outcomes into seen viewpoints when you look at the Byers (1959) and the algorithm from inside the Berry 
et al. (1945). The newest commission mistake against the fresh findings is discovered to be shorter than just 0.5% across the temperatures variety of 0°–35°C (Langlois 1967). Richards derived a several-training polynomial towards the saturation vapor pressure off water in the heat include ?50° in order to 140°C (Richards 1971). Tabata ideal an effective quadratic algorithm that produced the newest saturation vapor stress with a mean percentage error regarding 0.17% in the temperatures range between 0° to help you thirty-five°C (Tabata 1973).
