Conductivity Coefficients (ConUp0, ConUp1, ConUp2, ConUp3 and ConLo0, ConLo1, ConLo2, ConLo3)

Parameter Variable and Physical Definition

Temperature-Dependent Conductivity Coefficients: The coefficients determined to determine the relationship between conductivity and temperature through a third order polynomial, seen below.
