To express relative humidity as the ratio of vapor pressure PwPw to the saturation vapor pressure PwsPws at a given temperature, we can use the equation: RH=100×PwPwsRH=100×PwsPw Note that we always express relative humidity as a percentage. Another concept that we should be familiar with...

The ratio between the absolute humidity in a certain place and a given temperature and the maximum absolute humidity for that temperature is the relative humidity. How do you find absolute humidity? Absolute humidity is found relating a mass of water vapor with a volume of air. The absolute ...
An apparatus is described for the direct measurement of humidity mixing ratio. It is designed primarily for recording the turbulent fluctuations in the mixing ratio in the lower atmosphere, and is based on an electrical analogue of the wet-bulb equation, using dry- and wet-bulb thermocouples....
relative humidity- the ratio of the amount of water in the air at a give temperature to the maximum amount it could hold at that temperature; expressed as a percentage ratio- the relative magnitudes of two quantities (usually expressed as a quotient) ...
Equally important (which, again, may be part of your industry’s regulatory standards) is your required Test Uncertainty Ratio (TUR). This is how accurate your calibrator needs to be to give you confidence that your calibration is within a suitable margin of error. No calibration is ever goin...
The vapor concentration or absolute humidity of a mixture of water vapor and dry air is defined as the ratio of the mass of water vapor Mw to the volume V occupied by the mixture. Dv = Mw / V expressed in grams/m3 or in grains/cu ft The value of Dv can be derived as follows...
The result of this equation will give you a rough idea of how many years it will take for you to achieve breakeven by purchasing your own humidity generator / calibrator. For many businesses, the ROI of setting up humidity calibration in-house may be among the business' top investment opt...
