Relative Humidity (%) = Specific Humidity (g/kg) / Saturation Point (g/kg) x 100 Relative Humidity (%) = Mixing Ratio (g/kg) / Saturation Mixing Ratio (g/kg) x 100 Use this chart to determine relative humidity (%). Axes can be used for either Temperature (degrees C) vs Satura...
This chart shows the relationship between the dew point of air at atmospheric pressure vs. the dew point of air at 7 bar (~102 PSI) and 3 bar (~44 PSI). At higher working pressures, the pressure dew point (the temperature at which liquid falls out of the air) is also higher. Compr...

DeltaTrak’s Temperature/Humidity/Dew Point Circular Chart Recorder, Model 14013 (110V) and Model 14014 (220V), provides simultaneous monitoring of both temperature and relative humidity. This chart recorder is available in four different chart speeds: 12 hours, 24 hours, 7 days and 31 days. Ch...
The dew point can never be higher than the air temperature. Similarly, as the air temperature rises and/or the dew point drops, the relative humidity decreases because the air is getting farther away from saturation. This chart illustrates the key differences between relative humidity and dew ...
occurrence of cells with central minimum of temperature, and upward increasing anomalies in dew-point, i.e. occurrence of cells with central maximum, can be observed at any station, hence the occurrences of thunderstorms at that station can be predicted. Moreover, the two kinds of anomalies ...
A Quick Look at the Psychometric Chart Relating Dew Point, Temperature, Humidity [Click to enlarge any image] What is the Dew Point?: the dew point (Tdp) is thetemperature at which water vapor just starts to condense out of air that is cooling- for example when warm moisture-laden air ...

Dew forms when the air temperature drops to the dew point, causing moisture in the air to condense on cool surfaces. 9 How can due denote merit? Due can denote merit by referring to something that is deserved or appropriate, like giving someone their due respect. 9 Can dew be artificially...
hand, the relative humidity is the ratio between the current amount of water vapor in the air at a given temperature to the maximum amount of water vapor possible in the air at that temperature. The relative humidity is not an exact ratio between the current air temperature and dewpoint!
