  • Dew Point Calculator

    Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher dew point than dry air. Furthermore, the higher the relative humidity, the closer the dew point to the current air temperature, with

  • Understanding Pressure Dew Point vs. Atmospheric Dew Point

    Sep 05, 2012 · For example, consider compressed air leaving a dryer at 200 PSIG with a pressure dew point of -40º F/C @ 200 psig. If the pressure is eventually reduced to 100 psig, the pressure dew point will fall to -50 ºF @ 100 psig. If the air is further expanded to 5 psig, the pressure dew point becomes -77º F @ 5 psig. For this reason, the phrase pressure dew point (PDP) is commonly used. This term usually refers to the dew point of the compressed air at full line pressure.
