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 … WebFrom dry bulb temperature and relative humidity measurements, temperature humidity meters such as the Fluke 971 can calculate wet bulb temperature and dew point temperature, psychrometric points that are essential for HVAC evaluations and diagnostics.
