Relative humidity dry bulb wet bulb
WebPsychrometric tables give the relative humidity in percent considering the dry bulb and wet bulb temperatures. Take the temperature with both dry-bulb and wet-bulb thermometers. Find the difference between the two measurements, and then see where the numbers intersect on the chart below to get the RH%. WebThe 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 …
