  2. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). [8] [9] Air is a gas, and its volume varies with pressure and temperature, per Boyles law. Absolute humidity is defined as water mass per volume of air ...

    In this example the humidity ratio is 0.0126 kg water per kg dry air. Determining the effect of temperature change on relative humidity: For air of a fixed water composition or moisture ratio, find the starting relative humidity from the intersection of the wet and dry bulb temperature lines. Using the conditions from the previous example, the ...

  7. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    For example, a relative humidity of 100% means dew point is the same as air temp. For 90% RH, dew point is 3 °F lower than air temperature. For every 10 percent lower, dew point drops 3 °F.
