This video is p. The knowledge of only two of these values is enough to determine the state of the moist air including the content of water vapor and the sensible and latent energy enthalpy in the air. When air is at 100 relative humidity the dry bulb wet bulb and dew point temperatures are all the same. This one is the first of the humidity videos.

We will be covering how humidity is measured and what effect it has on the refrigeration cycle. By definition wet bulb temperature is the lowest temperature a portion of air can acquire by evaporative cooling only. The difference between the dbt and wbt is called as wet bulb depression. Thus the wet bulb temperature indirectly indicates the moisture content present in the air or we can say that it is affected by the relative humidity of the air.

The wet bulb temperature of the air is always less than the dry bulb temperature of air. Dry bulb temperature is a reading of the average molecular velocity of dry air but it does not take into account the actual heat content of the air or the evaporative cooling effect of the air. Indoor wet bulb measurement is useful for figurin. Wet bulb the lowest temperature that can be reached by the evaporation of water only measuring humidity.
