In a series circuit, the total resistance is simply the sum of the individual resistances. This is the logic underpinning Equation 48. However, the genius of this specific equation in the ASHRAE context lies in its inclusion of the ($R_i$ and $R_o$). 2009 ashrae hof chapter 4 equation 48 -pg 4.21--

Many engineers search for Equation 48 because they are debugging an old model. Here is the practical translation: supply air enthalpy ( )
