Relative Humidity for

WET BULB THERMOMETER

Calculator

(with concurrent inverse feature)


If, for example, outside air with initial conditions is heated without adding or extracting moisture the inside air will have the final conditions given by this calculator.

Type the input value in a box, click your mouse anywhere on the page or on a value that you may change next (or press tab key) to complete the calculation. Modify entries then click your mouse elsewhere on the page (or press tab key) for the values to agree.
for smooth operation start with the default values
DEW POINT - WET BULB - DRY BULB
F F F
C C C
[dew point] - [wet bulb] - [dry bulb]
DEW(100%) - corresponding WET - actual HUMIDITY
x 100% x 100% x 100%
dew point VAPOR PRESSURE - corresponding VAPOR PRESSURE - actual VAPOR PRESSURE
mm of Hg mm of Hg mm of Hg

Since the temperature cannot go below the 100% humidity point without reducing the specific humidity, the temperature for 100% humidity will be calculated instead; otherwise the relative humidity would go past 100%.

With an initial humidity of 100% the initial temperature will be the dew point for the final temperature and relative humidity.

The variables that can be independent are in capitals.
