1. Key definitions of relative humidity
1.1 Saturation vapour pressure in pure phase
This is the vapor pressure in a state of indifferent equilibrium with a flat surface of pure water ( ) or ice ( ), at the same temperature and pressure.
In other words, this is the maximum value that the partial pressure of water vapour can reach at this temperature. Above this value, condensation occurs.
Saturation vapour pressures ...
