Get the best deals on Sony PlayStation 5 Consoles and upgrade your gaming setup with a new gaming console. This formula is derived from Ideal gas law, and adapted for water vapor. The mixing ratio is defined as the mass of water vapor divided by the mass of dry air. It mainly changes with temperature, relative humidity, pressure and hence with altitude (take a look on the air density table below). If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls; this is because less vapor is needed to saturate the air. e s saturation vapour pressure [kPa], e a actual vapour pressure ... and minimum (RH min) relative humidity, from the maximum (RH max), or from mean relative humidity (RH mean ... and daylight hours (N) for a specific day of the month can be computed using Equations 21 and 34 or can be selected from Tables 2.5 and 2.6 in Annex 2. e s is the liquid water saturation vapor pressure at air temperature, given approximately by the empirical equation When air does not have any more capacity to hold water content, it is called a saturation point.
