Calculate dewpoint wet bulb temperature from relative humidity.
Psychrometric calculations estimates wet bulb temperature relative humidity and dry bulb temperature based on perfect gas relations published in 2009 ashrae fundamentals handbook.
Construction different materials react differently to different humidities so this temperature is needed when designing a building in different climates.
A simple online weather calculator to find the dewpoint and the wet bulb temperature by knowing the values of relative humidity temperature and actual station pressure.

Using the calculator we see that this is 58 4.
The wet bulb temperature might not be a widely known measure but it has some valuable functions.
The entry required is in fahrenheit degrees.
The easiest way to do this is entering the dry and wet bulb temperatures into the calculator above and then click calculate.
If partly saturated air is cooled without changing its pressure or amount of water vapour a point is reached when it becomes saturated.
Snowmaking snow production needs low temperatures and when the humidity decreases the temperature rises.
Enter a temperature wet bulb and actual station pressure.
Wet bulb temp c.
This script will determine the relative humidity from the entered dry and wet bulb temperatures data.
For example if we have a dry bulb temperature of 20 and a wet bulb temperature of 15 what is the relative humidity.
Dewpoint is the atmospheric temperature below which water droplets begin to condense and become dew.
Altitude select ip units for inputs.
If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.
