Heat Transfer by Conduction Resistance through a Cylindrical Wall

Heat Transfer by Conduction resistance through a Cylindrical Wall Formula

\(\large{ R_t =  \frac   {  ln \;  \left(   \frac  {r_2 }  { r_1 } \right) }   { 2 \; \pi \; k \; l  }   }\)

Where:

\(\large{ R_t }\) = thermal resistance

\(\large{ l }\) = length of material

\(\large{ ln }\) = natural logarithm

\(\large{ \pi }\) = Pi

\(\large{ r_1 }\) = radius inside diameter (ID)

\(\large{ r_2}\) = radius outside diameter (OD)

\(\large{ k }\) = thermal conductivity
