Dry bulb vs dew point
WebThe dry-bulb temperature ( DBT) is the temperature of air measured by a thermometer freely exposed to the air, but shielded from radiation and moisture. DBT is the temperature that is usually thought of as air … Webrelative humidity of 100% indicates that the dew point is equal to the current temperature. This relationship between dew point and relative humidity is given in Table C-1. Visible and Concealed Condensation. Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew . point.

So there you have it.
When the air temperature is high, the human body uses the evaporation of perspiration to cool down, with the cooling effect directly related to how fast the perspiration evaporates. The rate at which perspiration can evaporate depends on how much moisture is in the air and how much moisture the air can hold. If the air is already saturated with moisture (humid), perspiration will not evaporate. The body's thermoregulation will produce perspiration in an effort to keep the body at …
