Water moisture content of humid air calculator

When analysing HVAC or other thermal applications, when the humidity of air needs to be modelled, some kind of multiphase solution is chosen. In many cases the fraction of water in the air is required as input variable for the CFD algorithm. The calculator below calculates the different mass fractions of O2, N2 and H2O in air.

Humidity calculator

Calculate the fractions of O2, N2 and H2O in humid air for a given temperature and relative humidity. The calculation is based on an atmospheric pressure of 105 Pa. Calculation only for temperatures between 0 and 100 °C.
