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...
The Wet Bulb temperature is always between the Dry Bulb temperature and the Dew Point. For the wet bulb, there is a dynamic equilibrium between heat gained because the wet bulb is cooler than the surrounding air and heat lost because of evaporation. The wet bulb temperature is the temperature...
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 ...
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 of the three following parameters: wet bulb temperature, dry bulb temperature and dew point ...
