If temperature rise again, repeat process. For example, 70F with a relative humidity of 80% feels much hotter than 70F with 50% RH. Calculate relative humidity RH using the formula, RH = 100 {exp[17.625 Dp/(243.04 + Dp)]/exp[17.625 T/(243.04 + T)]}. Questions? Web100% humidity feels like walking around in cotton batten that's been soaked in water the temperature of your shower. An outdoor temperature of 60 degrees is often accompanied by a dew point reading of 50 degrees, sometimes higher. Its worth noting that absolute humidity is the actual amount of water suspended in the air regardless of the temperature (its measured in grams of water vapor per cubic meter of air). This is an archived article and the information in the article may be outdated. Is dry or wet heat worse? Water vapor enters the atmosphere by evaporating from the large bodies of water on the Earths surface including lakes, oceans, and seas. Yet, in this scenario, code requires an intentional mechanical means of drying, so it now makes sense to proactively seal, tune-up, of replace old duct work or equipment with modern ducting and an ADJUSTABLE DRYING MECHANISM so you can be deliberate and fine-tune the crawlspace conditions rather than over-drying it by accident. You can choose from whole-house dehumidifiers or stand-alone tabletop systems and larger cart-style ones on wheels. You could be mistaken to think the mold situation is worse just because the air-born mold was higher. Humidity is a measurement of moisture in the air. Educational Resources Estimating mugginess using relative humidity can be misleading since a high relative humidity doesn't necessarily mean high mugginess. It would feel much more "humid" on the 80 degree day with 50% relative humidity than on the 30 degree day with a 100% relative humidity.
