Local Heat Transfer Resistance in Heat Transfer Formulas

Local Heat Transfer Resistance is the ratio of the temperature difference, dT, to the heat transfer Q. This is analogous to Ohm’s law. And is denoted by HT_Resistance. Local Heat Transfer Resistance is usually measured using the Kelvin per Watt for Thermal Resistance. Note that the value of Local Heat Transfer Resistance is always positive.
