WC VA 2 Humidity chart for wet and dry bulb thermometersTRADA Technology
also known as a psychrometric diagram or a Mollier chart. This chart tells you the moisture content of the air if you know two of the three following parameters: wet bulb temperature, dry bulb temperature and dew point
When air passes over the cloth to evaporate the water, the evaporative cooling shows the wet bulb temperature on the thermometer. But why do we care about this measurement? We often use this temperature to find the dew point and/or humidity as we compare it to the dry bulb air temperature...

By combining the dry bulb and wet bulb temperature in apsychrometric chartorMollier diagramthe state of the humid air can be determined. Lines of constant wet bulb temperatures run diagonally from the upper left to the lower right in thePsychrometric chart. ...
Climate change causes extreme heat and high humidity in some regions. The wet-bulb temperature (Tw) is a heat stress index, and the threshold is 35 °C. It is difficult to measure the value of Tw using a psychrometer, but the Tw value can be calculated u
It includes a dry-bulb thermometer, a wet-bulb thermometer and a psychrometric chart - a graph that plots the relationships between the dry and wet-bulb temperature, relative humidity, and dew point at constant pressure. By definition, wet-bulb temperature is the lowest temperature a portion of...
If the dry bulb temperature of air is18oCand the web bulb temperature is12oC- then the difference between them is 6oC. By using the table above the relative humidity is approximately49% Example - the State of Air in the Psychrometric Chart ...
The difference between the wet bulb and dry bulb temperatures doesn't directly produce a relative humidity reading. You usually have to consult a wet bulb chart, also known as a psychrometric diagram or a Mollier chart. This chart tells you the moisture content of the air if you know two ...
