Análise de modelos de cálculo do fator de ajuste de valores de condutividade elétrica quanto ao efeito da temperatura.

Abstract

Electrical conductivity (CE) is affected by temperature (T), therefore it is necessary to express this variable for a standard temperature (25 oC). In this way, it is necessary to propose models for calculating an adjustment factor in order to standardize the CE values under various temperatures to the temperature of 25oC. There are several available models for calculating this factor in the literature, however, there is no information about comparisons among these models that may be possible to recommend one or other as the most adequate. Five models for calculating this factor were evaluated in a range of 0 to 50oC. The degrees of convergence and divergence of the values of the factor from the models were analyzed for this range of temperature.
