Wet bulb dry bulb chart fahrenheit.

You may plan for more rest but not less. Dry bulb temperature and. At lower humidity the wet bulb temperature is lower than dry bulb temperature because of evaporative cooling. Wet bulb temperature t wb.

Constant dry bulb temperatures appear as vertical lines in the psychrometric chart. The wet bulb temperature is the adiabatic saturation temperature. At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. The wet bulb temperature wbt is the temperature read by a thermometer covered in water soaked cloth wet bulb thermometer over which air is passed.

It includes a dry bulb thermometer a wet bulb thermometer and a psychrometric chart a graph that plots the relationships between the dry and wet bulb temperature relative humidity and dew point at constant pressure. Dry bulb temperature t db can be measured with a simple thermometer as shown above. Wet bulb temperature t wb. These are minimum rest periods.

The dry bulb temperature is an indicator of heat content and is shown along the bottom axis of the psychrometric chart. Wet bulb temperature t wb can be measured with a standard thermometer with some wet clothing cotton or similar around the bulb. The wet bulb temperature is the temperature of adiabatic saturation. By definition wet bulb temperature is the lowest temperature a portion of air can acquire by evaporative cooling only.

Note that continuously air flow around the thermometer is important to evaporate. This is the temperature indicated by a. Air humidity can be estimated by measuring.
