饱和蒸汽汽化潜热
饱和蒸汽压计算方法
There is a large number of saturation vapor pressure equations used to calculate the pressure of water vapor over a surface of liquid water or ice. This is a brief overview of the most important equations used. Several useful reviews of the existing vapor pressure curves are listed in the references. Please note the updated discussion of the WMO formulation. 1) Vapor Pressure over liquid water
