ABSTRACT: An equation model
for calculating the adiabatic temperature of the wet-bulb thermometer has been
obtained empirical fit through a meteorological database, specificly a trough
relative humidity and air temperature. A comparison of the results of
calculations with the use of this equation and from meteorological database was
made. The model deducted of the comparison is valid for a dry bulb temperature
range of 3°C to 35°C and for relative humidity percentage in a range of 7% to
97%. Normalized errors are less than 5.5%. It means a maximum variation of 0.55°C
from data. However, this variation from error represents only 3.6% of the data
sample. The equation model was satisfactory.
