How is relative humidity computed
Web11 sep. 2016 · Therefore relative humidity can be calculated from measured air temperature and dew point. Sample Question 2: What is the relative humidity of an air sample at 23 C if the dew point of the sample is 19 C? Using equation 3 to determine the water vapor pressure at 19 C and at 23 C equals 22.063 millibars and 28.21 millibars, … http://iridl.ldeo.columbia.edu/dochelp/QA/Basic/dewpoint.html
