Web25 nov. 2024 · Relative humidity: RH is the ratio of the mole fraction of water vapour to the moles’ fraction of saturated moist air at the same temperature and pressure. RH is dimensionless and is usually expressed as a percentage. Lines of contrast RH reflect the physics of air and water; they are determined via experimental measurement. WebTo evaluate relative humidity, wet bulb temperature, and dew point, HVAC technicians traditionally used a sling psychrometer and psychrometric chart. Nowadays they use "humidity" meters that are accurate, more convenient, and usable in confined locations unsuitable for sling psychrometers. Temperature-humidity meters

WebRelative humidity is determined by using the actual vapor pressure divided by the saturation vapor pressure (see below). Meteorologists also use dewpoint temperature as a measure of the amount of water vapor in the atmosphere. This is the temperature at which the atmosphere becomes saturated and dew starts to form.
