Relative humidity to humidity ratio
WebRelative Humidity. The relative humidity is used to find the air’s water vapour content. The relative humidity is defined as the ratio between the amount of moisture in the air at a … WebThe specific humidity ω is then evaluated using the relative humidity φ as a parameter to produce the various relative humidity curves (blue lines) as follows: where P is the standard atmospheric pressure 101.325 [kPa]. The saturation curve (100% relative humidity) also known as the dew point curve is drawn as a red line.

Atmospheric humidity is a measure of water held in the air as a gas. Water can be solid (ice), liquid (water) or a gas (vapour). The vapour component makes up about 99% of all water held in the atmosphere.
Humidity ratio by mass can be expressed as 1. the ratio between the actual mass of water vapor present in moist air - to the mass of the dry air Humidity ratio is normally expressed in kilograms (or pounds) of water vapor per kilogram (or pound) of dry air.
