WebApr 1, 2024 · What is Wet Bulb Temperature? When water evaporates into the air it creates a cooling effect, but the amount of this cooling varies depending on the overall air temperature and the relative humidity. The wet-bulb temperature is the lowest possible temperature that air can be cooled down to by the evaporation of water alone, given … WebNot to be used for operational use) The WetBulb Globe Temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind …
WebMay 29, 2007 · With this sensible heat ratio, and with the right amount of air moving over the cooling coil, I would be looking for supply dry bulb temperatures to be around 55-56 degrees and the wet bulb temperature to be around 53-54 degrees. I would be obtaining this temperature right off the cooling coil, not at a supply vent somewhere in the house. http://www.bom.gov.au/climate/averages/climatology/relhum/calc-rh.pdf

The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked (water at ambient temperature) cloth (a wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the … See more If a thermometer is wrapped in a water-moistened cloth, it will behave differently. The drier and less humid the air is, the faster the water will evaporate. The faster water evaporates, the lower the thermometer's … See more The thermodynamic wet-bulb temperature is the temperature a volume of air would have if cooled adiabatically to saturation by evaporation of water … See more The adiabatic wet-bulb temperature is the temperature a volume of air would have if cooled adiabatically to saturation and then compressed … See more The wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature. If there is 100% humidity, dry-bulb and wet-bulb temperatures are identical, making the wet-bulb depression equal to zero in such conditions. See more The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach … See more Wet-bulb temperature is measured using a thermometer that has its bulb wrapped in cloth—called a sock—that is kept wet with distilled water via wicking action.
