dew point temperaturehumid aircondensationmeasurementphotoelectric systemAn instrument is designed and constructed to allow direct measurements to be taken of the dew point temperature of humid air. The principle uses the photoelectric system to detect the instant at which the vapour flowing over a ...
A mass of air at 30°C has a percent saturation of 60%. Find the absolute humidity, wet-bulb temperature and dew point of that air. Solution: All the properties are obtainable from the psychrometric chart in Appendices (Figure A.2) ...

This dew point calculator can be used to explore the relationship between dew point, temperature, and relative humidity, without the need for a dew point chart. If you have ever wondered "what is dew point?" or how to calculate relative humidity in certain conditions, then this calculator is...
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 ...

If you know the incoming air RH, then with a psychrometric chart, you should be able to predict any other state, such as dew point temperature, enthalphy of the air, energy required to raise/lower the temperature, etc. Check an ASHRAE book or professional society if you do not have a ...
A psychrometric chart shows the relationship between air temperature, humidity, and other properties of moist air using a graphical representation. Psychrometry can determine properties like dew point, wet-bulb temperature, and enthalpy using the chart and equations. HVAC (heating, ventilation, and ai...
Dew Point Example 2: in the psychrometric chart given below, read up from 50 degC dry bulb temperature to the 20% RH curve, then follow the horizontal line from that point to the left to the outermost curve on the chart. If you don't go blind following this chart (click to enlarge ...
Make dew point your friend High relative humidity certainly does happen. It usually coincides with lower air temperatures, though. As the temperature rises, the relative humidity goes down. This morning when I awoke, for example, the relative humidity here in the Atlanta area was 87%. Although...
