Definition

quotient of mass of water vapour and mass of dry gas:

r = \frac{m}{m_{d}}

where $m$ is mass (ISO 80000-4: Mechanics) of water vapour and $m_{d}$ is mass of dry gas

quotient de la masse de vapeur d'eau par la masse de gaz sec:

r = \frac{m}{m_{d}}

où $m$ est la masse (ISO 80000-4: Mechanics) de vapeur d'eau et $m_{d}$ est la masse de gaz sec

Notes

Mass ratio of water vapour to dry gas at saturation is denoted $r_{sat}$ .

Mass ratio of water vapour to dry gas is also called mixing ratio.

Le rapport de la masse de vapeur d'eau à la masse de gaz sec à saturation est noté $r_{sat}$ .

Le rapport de la masse de vapeur d'eau à la masse de gaz sec est également appelé rapport de mélange.
