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
