The Wet Bulb, Dew Point and Apparatus Dew Point are iterated using a curve fitted Enhancement Factor. Other properties are calculated using equations and Tables from ASHRAE 2009 Fundamentals and 2008 HVAC Systems and Equipment.
generally easy to determine are the dry bulb temperature and the wet bulb temperature. The dry bulb temperature is simply the temperature of the air as determined by some sensor such as a thermometer. This determines the horizontal position on the psychrometrc chart. In order
Online Psychrometric Chart. Calculation of psychrometric parameters
This psychrometric calculator provides web bulb temperature and other psychrometric calculation in addition to a psychrometric chart. Either wet bulb temperature or relative humidity can be selected as input. You can enter also altitude, that is necessary to make corrections for the atmospheric pressure.
Wet bulb temperature (WB): The wet bulb temperature is used to measure the water content of moist air. It is obtained by passing air over a thermometer that has a wet wick over its sensing bulb. The drier the air, the more water will evaporate from the wick which lowers the reading on the thermometer.
