Just one example, if the current temperature is around 75 degrees and there is a humidity reading of zero percent, it feels like the environment is at 69 degrees. 1) Hot air can hold more water. A hygrometer is another great way to adjust humidity levels. To express relative humidity as the ratio of vapor pressure PwP_wPw to the saturation vapor pressure PwsP_{ws}Pws at a given temperature, we can use the equation: Note that we always express relative humidity as a percentage. If nausea occurs, discontinue use. Local Observations Drought Monitor 3) Wood takes months to absorb and release water vapors, thus the average conditions in a crawlspace are much more relevant than the highs and lows. This happens because when the air is saturated with water, your sweat cant evaporate as quickly. Current Hazards Rapid and strong pulse.
