Wet bulb dry bulb chart fahrenheit.

The wet bulb temperature is the temperature of adiabatic saturation. The dry bulb temperature is an indicator of heat content and is shown along the bottom axis of the psychrometric chart. Constant dry bulb temperatures appear as vertical lines in the psychrometric chart or horizontal lines in the mollier diagram. Wet bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin.

Wet bulb temperature t wb. The wet bulb temperature is the adiabatic saturation temperature. Environmental heat stress categories are given in wet bulb globe temperature values. 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.

Wet bulb temperature t wb can be measured with a standard thermometer with some wet clothing cotton or similar around the bulb. Dry bulb temperature t db can be measured with a simple thermometer as shown above. These are minimum rest periods. Air humidity can be estimated by measuring.

You may plan for more rest but not less. Note that continuously air flow around the thermometer is important to evaporate. This is the temperature indicated by a. 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 and. At 100 relative humidity the wet bulb temperature is equal to the air temperature dry bulb temperature. Constant dry bulb temperatures appear as vertical lines in the psychrometric chart.
