Wet-bulb temperature at 30 °C and 50 % humidity

The wet bulb shows the limit of adiabatic cooling: at 30 °C and 50 % it is about 22 °C and the enthalpy of the air is about 64 kJ/kg.

Frequently asked questions

Why know the wet-bulb temperature?
It is the minimum temperature to which water can be cooled by evaporation (cooling tower) and the limit of the drying rate.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
