Wet-Bulb Temperature from Pressure, Relative Humidity, and Air Temperature

ABSTRACT: The algorithms currently in use for calculating the wet-bulb temperature from pressure, relative humidity, and air temperature have errors of a degree or more. Here, the equation for the thermodynamic wet-bulb temperature is derived using the Rankine?Kirchhoff approximations, which are highly accurate for meteorological and climatological applications. Likewise, equations are derived …
