Wet Bulb Temp
Find the wet-bulb temperature (°C) if the relative humidity is 60% and the actual air temperature is 19°C.
Expand Hint
Properties of an air-water vapor mixture at a fixed pressure are given in graphical form on a psychrometric chart as provided in problem statement. When the system pressure is 1 atm, an ideal-gas mixture is assumed.
Hint 2
Properties of an air-water vapor mixture at a fixed pressure are given in graphical form on a psychrometric chart as provided in problem statement. When the system pressure is 1 atm, an ideal-gas mixture is assumed.
In the psychrometric chart, let’s find where the 19°C dry bulb temperature (the temperature of air measured by a thermometer freely exposed to air) intersects with the 60% humidity curve (2). The wet-bulb line that crosses this intersection is what the problem is asking for (3).
The wet-bulb temperature is around 14.2°C.
14.2°C
